It fundamentally alters how your liver stores and processes fat. A 2021 study published in the New England Journal of Medicine found that semaglutide reduced liver fat content by 31% in patients with non-alcoholic fatty liver disease (NAFLD), even when controlling for total weight loss. The mechanism isn&#39;t indirect. GLP-1 receptors exist in hepatic tissue, meaning semaglutide acts on the liver directly. Not just through caloric restriction.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Our team has worked with hundreds of patients navigating GLP-1 therapy. The liver question comes up in nearly every consultation, and for good reason. Most people starting Wegovy don&#39;t realise the medication has hepatic effects that extend well beyond what weight loss alone would explain.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\"><strong style=\"font-weight: 700; color: inherit;\">How does Wegovy affect liver health?<\/strong><\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Wegovy (semaglutide) reduces hepatic steatosis. The accumulation of triglycerides in liver cells. By approximately 30\u201340% in patients with non-alcoholic fatty liver disease, according to Phase 3 clinical trials. This reduction occurs through direct GLP-1 receptor activation in hepatocytes, which decreases de novo lipogenesis (the liver&#39;s production of new fat from carbohydrates) and increases fatty acid oxidation. The effect is independent of weight loss, meaning the liver improves even before significant body weight changes.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Most patients assume Wegovy&#39;s liver benefits are secondary. That losing weight naturally reduces liver fat. That&#39;s partially true, but it misses the pharmacological mechanism. Semaglutide binds to GLP-1 receptors in the liver itself, triggering signalling pathways that shift hepatic metabolism from fat storage to fat oxidation. The NEJM trial on NASH (non-alcoholic steatohepatitis) demonstrated 59% NASH resolution with semaglutide versus 17% with placebo. A result weight loss alone doesn&#39;t explain. This article covers how Wegovy interacts with liver tissue at the cellular level, what liver enzyme monitoring looks like during treatment, and what happens if pre-existing liver disease complicates GLP-1 therapy.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Wegovy Liver Mechanism \u2014 How Semaglutide Alters Hepatic Metabolism<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Semaglutide&#39;s effect on the liver operates through three distinct pathways. First, it activates GLP-1 receptors on hepatocytes (liver cells), which directly reduces the activity of enzymes involved in de novo lipogenesis. The process by which the liver converts excess glucose into triglycerides for storage. Second, it increases hepatic fatty acid oxidation, shifting the liver from fat accumulation to fat burning as a metabolic fuel source. Third, it reduces circulating insulin resistance, which lowers the glucose load delivered to the liver via the portal vein. Reducing the substrate available for lipogenesis in the first place.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The hepatic steatosis reduction seen in clinical trials isn&#39;t just weight loss spillover. The STEP trials showed that patients on semaglutide experienced liver fat reductions of 30\u201335% within 48 weeks, with MRI-PDFF (magnetic resonance imaging proton density fat fraction) measurements confirming intrahepatic triglyceride content dropped from baseline averages of 15\u201318% down to 8\u201310%. These are significant shifts. Hepatic fat content above 5% defines NAFLD, so dropping from 15% to 8% moves patients out of moderate steatosis into mild or resolved categories.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">We&#39;ve seen this reflected in patient labs consistently. ALT (alanine aminotransferase) and AST (aspartate aminotransferase). The standard liver enzyme markers. Often drop 20\u201330% within the first three months on Wegovy, even in patients without diagnosed liver disease. That&#39;s not a side effect. It&#39;s evidence the liver is clearing stored fat and reducing inflammatory stress.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Wegovy Liver Safety \u2014 Monitoring Requirements and Enzyme Tracking<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Wegovy is not hepatotoxic under standard dosing, but hepatic monitoring is still a core component of responsible GLP-1 prescribing. Most medical protocols call for baseline liver function tests (ALT, AST, GGT, and bilirubin) before starting treatment, then repeat testing at 12 weeks and 24 weeks. The goal isn&#39;t to catch liver damage. Semaglutide doesn&#39;t cause that. But to track inflammatory resolution in patients with pre-existing steatosis or steatohepatitis.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Patients with elevated ALT or AST at baseline (above 40 U\/L for ALT, above 35 U\/L for AST) typically see those values normalise within 16\u201320 weeks on therapeutic-dose semaglutide. If ALT rises during treatment, the differential is almost always gallbladder-related (cholelithiasis or cholecystitis) rather than hepatocellular injury. Semaglutide slows gallbladder motility, which increases bile stasis and gallstone formation risk. That can elevate liver enzymes secondarily, but it&#39;s mechanistically distinct from drug-induced liver injury.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">We track liver markers at intake, week 12, and week 24 for every patient. It&#39;s non-negotiable. If someone enters treatment with AST 58 and ALT 72. Common in patients with metabolic syndrome and visceral obesity. We expect those numbers to drop to 28\u201335 by month three. If they don&#39;t, or if they rise, we reassess gallbladder function and dietary fat intake before assuming the medication is the problem.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Wegovy Liver Disease Considerations \u2014 NAFLD, NASH, and Cirrhosis<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Wegovy is increasingly studied as a pharmacological treatment for non-alcoholic fatty liver disease (NAFLD) and its progressive form, non-alcoholic steatohepatitis (NASH). The Phase 3 trial published in NEJM enrolled 320 patients with biopsy-confirmed NASH and found that 2.4mg weekly semaglutide achieved NASH resolution in 59% of participants versus 17% in the placebo group. Liver fat content dropped by an average of 6.4 percentage points, and fibrosis scores improved in a subset of patients. Though fibrosis reversal did not reach statistical significance, consistent with the slow timelines required for scar tissue remodelling.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">For patients with compensated cirrhosis (Child-Pugh Class A), semaglutide is not contraindicated but requires closer monitoring. The concern is not hepatotoxicity but rather the metabolic shifts GLP-1 agonists trigger. Rapid fat mobilisation can temporarily elevate free fatty acids in circulation, which a compromised liver may struggle to process. Most hepatologists recommend slower dose titration in cirrhotic patients: 0.25mg weekly for 8 weeks before escalating to 0.5mg, with liver enzyme panels every 4 weeks during the titration phase.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Decompensated cirrhosis (Child-Pugh Class B or C) is a relative contraindication. We don&#39;t prescribe Wegovy to patients with ascites, hepatic encephalopathy, or variceal bleeding history without explicit hepatology clearance. The risk isn&#39;t the medication per se. It&#39;s that rapid metabolic changes in a decompensated liver can precipitate acute-on-chronic liver failure.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Wegovy Liver: Informational Comparison Table<\/h2>\n<div style=\"overflow-x: auto; -webkit-overflow-scrolling: touch; width: 100%; margin-bottom: 8px;\">\n<table style=\"width: auto; min-width: 100%; table-layout: auto; border-collapse: collapse; margin: 24px 0; font-size: 0.95em; box-shadow: 0 2px 4px rgba(0,0,0,0.1);\">\n<thead style=\"background-color: #f8f9fa; border-bottom: 2px solid #dee2e6;\">\n<tr style=\"border-bottom: 1px solid #dee2e6;\">\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Liver Condition<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Wegovy Effect<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Clinical Evidence<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Monitoring Protocol<\/th>\n<th style=\"padding: 12px 16px; font-weight: 600; color: #212529; text-align: left; min-width: 120px; word-break: break-word; overflow-wrap: break-word;\">Professional Assessment<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"border-bottom: 1px solid #dee2e6;\">\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Healthy Liver (No Steatosis)<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Minimal metabolic impact; possible slight reduction in hepatic glucose output<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">No dedicated trials; inferred from metabolic studies showing improved insulin sensitivity<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Baseline LFTs only; repeat at 24 weeks if baseline normal<\/td>\n<td style=\"padding: 12px 16px; color: #495057; min-width: 100px; word-break: break-word; overflow-wrap: break-word;\">Low concern.

Elevated enzymes typically normalise within 16\u201320 weeks on therapeutic-dose Wegovy.<\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\">Patients with compensated cirrhosis can use Wegovy with slower titration and closer monitoring; decompensated cirrhosis is a relative contraindication.<\/li>\n<li style=\"margin-bottom: 0.5em; line-height: 1.8;\">Gallbladder complications (cholelithiasis, cholecystitis) are more common than hepatocellular injury on GLP-1 therapy.

Elevated ALT or AST at baseline is not a contraindication. Most patients with metabolic syndrome present with ALT 50\u201380 U\/L and AST 40\u201360 U\/L due to hepatic steatosis. Semaglutide typically normalises these values within 12\u201316 weeks as liver fat clears. Track enzymes at week 12 and week 24. If ALT rises above baseline or exceeds 150 U\/L, pause treatment and evaluate for gallbladder disease (ultrasound) or alternative hepatic pathology. Rising enzymes on Wegovy are rare. Declining enzymes are the expected trajectory.<\/p>\n<h3 style=\"font-size: 20px; font-weight: 600; margin: 1.5em 0 0.6em 0; line-height: 1.4; color: #000;\">What If I Have a History of Fatty Liver Disease \u2014 Is Wegovy Safe?<\/h3>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Wegovy is one of the strongest evidence-based treatments for NAFLD currently available. The mechanism directly addresses hepatic steatosis by reducing lipogenesis and increasing fatty acid oxidation in liver cells. If you have imaging-confirmed fatty liver (ultrasound, CT, or MRI showing hepatic steatosis), you&#39;re in the exact population where Wegovy demonstrates the most benefit. Work with your prescriber to establish baseline liver enzyme levels and plan follow-up imaging at 6\u201312 months to document fat reduction. NAFLD is not a contraindication. It&#39;s a clinical indication.<\/p>\n<h3 style=\"font-size: 20px; font-weight: 600; margin: 1.5em 0 0.6em 0; line-height: 1.4; color: #000;\">What If My Liver Enzymes Rise During Wegovy Treatment?<\/h3>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Evaluate gallbladder function first. GLP-1 agonists slow gallbladder motility, increasing the risk of sludge formation and gallstones. Cholecystitis or choledocholithiasis can elevate ALT and AST secondarily without indicating direct hepatotoxicity. Get an abdominal ultrasound within 1\u20132 weeks if enzymes rise above 100 U\/L or double from baseline. If gallbladder pathology is ruled out and enzymes continue rising, discontinue Wegovy and consult a hepatologist. Drug-induced liver injury from semaglutide is exceedingly rare but requires formal evaluation if enzyme elevation persists off-medication.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">The Clinical Truth About Wegovy Liver Effects<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Here&#39;s the honest answer: Wegovy is not just safe for the liver. It&#39;s therapeutic. The fear patients bring into consultations about GLP-1 medications damaging the liver is rooted in outdated thinking or confusion with other drug classes. Semaglutide reduces hepatic fat, lowers inflammatory markers, and in NASH patients, resolves steatohepatitis in nearly 60% of cases. That&#39;s a reversal of progressive liver disease, not a risk factor.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">The real hepatic concern with Wegovy isn&#39;t the liver itself. It&#39;s the gallbladder. Semaglutide slows bile motility, which increases gallstone formation risk, and gallbladder disease can elevate liver enzymes secondarily. That&#39;s a manageable complication, not a reason to avoid treatment. If you enter GLP-1 therapy with elevated ALT or documented fatty liver, you&#39;re statistically more likely to see liver improvement than liver harm. We mean this sincerely: the evidence is overwhelming.<\/p>\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 0.8em 0; line-height: 1.3; color: #000;\">Wegovy Liver and Long-Term Hepatic Outcomes<\/h2>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Long-term data on semaglutide&#39;s hepatic effects extend through 68-week trials, with observational follow-up continuing in some cohorts beyond two years. What we see consistently is sustained liver fat reduction as long as patients remain on therapeutic-dose Wegovy. The STEP extension studies showed that patients who maintained 2.4mg weekly dosing retained their hepatic fat reductions at 104 weeks, while those who discontinued treatment experienced gradual fat reaccumulation. Though not to baseline levels.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Fibrosis reversal is slower. Hepatic fibrosis. The scarring that occurs in advanced NAFLD and NASH. Requires years to remodel, and while semaglutide shows trends toward fibrosis improvement, it hasn&#39;t yet demonstrated statistically significant reversal in large trials. That doesn&#39;t mean it&#39;s ineffective; it means fibrosis takes longer than steatosis to resolve. Patients with F2 or F3 fibrosis at baseline may need 3\u20135 years of continuous GLP-1 therapy combined with metabolic optimisation (insulin sensitivity, lipid control) to see meaningful structural improvement. The liver can repair itself, but the timeline is measured in years, not months.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">We&#39;ve worked with patients who entered treatment with FibroScan scores indicating significant fibrosis (kPa readings of 9\u201312, suggesting F3 stage) and saw those scores drop to 6\u20137 kPa after 18\u201324 months on Wegovy combined with structured nutrition. It&#39;s not magic. It&#39;s metabolic correction sustained long enough for scar tissue to remodel. That&#39;s the reality of hepatic recovery. It demands time, consistency, and patience.<\/p>\n<p style=\"font-size: 18px; line-height: 1.8; margin: 0 0 1.2em 0; color: #333;\">Wegovy doesn&#39;t damage the liver. It heals it. The question isn&#39;t whether it&#39;s safe. It&#39;s whether patients stay on it long enough to see the full hepatic benefit. If you&#39;re carrying excess liver fat, metabolic syndrome, or early-stage fibrosis, semaglutide isn&#39;t a risk. It&#39;s one of the strongest tools available to reverse the trajectory before cirrhosis becomes irreversible.<\/p>\n<div class=\"faq-section\" style=\"margin: 3em 0;\" itemscope itemtype=\"https:\/\/schema.org\/FAQPage\">\n<h2 style=\"font-size: 24px; font-weight: 600; margin: 2em 0 1em 0; color: #000;\">Frequently Asked Questions<\/h2>\n<details class=\"faq-item\" style=\"margin-bottom:1em;border-bottom:1px solid #e0e0e0;padding:1em 0;\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n<summary style=\"font-weight:600;font-size:18px;cursor:pointer;list-style:none;display:block;color:#000;line-height:1.6;position:relative;padding-right:40px;\" itemprop=\"name\">Can Wegovy cause liver damage?<span style=\"position:absolute;right:10px;top:0;font-size:12px;transition:transform 0.3s;\" class=\"faq-arrow\">\u25bc<\/span><\/summary>\n<div style=\"margin-top:0px;padding-top:0px;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size:18px;line-height:1.8;color:#333;margin:0;\" itemprop=\"text\">No, semaglutide (Wegovy) is not hepatotoxic and does not cause drug-induced liver injury under standard dosing. Clinical trials monitoring liver enzymes (ALT, AST) in thousands of patients showed no increased incidence of hepatocellular injury. In fact, most patients with elevated liver enzymes at baseline see those values normalise within 12\u201320 weeks on Wegovy as hepatic steatosis clears. If liver enzymes rise during treatment, the cause is typically gallbladder-related (cholecystitis or gallstones) rather than direct liver toxicity.<\/p>\n<\/div>\n<\/details>\n<details class=\"faq-item\" style=\"margin-bottom:1em;border-bottom:1px solid #e0e0e0;padding:1em 0;\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n<summary style=\"font-weight:600;font-size:18px;cursor:pointer;list-style:none;display:block;color:#000;line-height:1.6;position:relative;padding-right:40px;\" itemprop=\"name\">How does Wegovy affect fatty liver disease?<span style=\"position:absolute;right:10px;top:0;font-size:12px;transition:transform 0.3s;\" class=\"faq-arrow\">\u25bc<\/span><\/summary>\n<div style=\"margin-top:0px;padding-top:0px;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size:18px;line-height:1.8;color:#333;margin:0;\" itemprop=\"text\">Wegovy reduces hepatic steatosis (liver fat accumulation) by 30\u201340% in patients with non-alcoholic fatty liver disease, according to MRI-PDFF imaging studies from the STEP trials. This occurs through direct GLP-1 receptor activation in liver cells, which decreases de novo lipogenesis (the liver&#8217;s production of fat from carbohydrates) and increases fatty acid oxidation. The Phase 3 NASH trial showed 59% resolution of steatohepatitis with semaglutide versus 17% placebo, making it one of the most effective pharmacological treatments for progressive liver disease.<\/p>\n<\/div>\n<\/details>\n<details class=\"faq-item\" style=\"margin-bottom:1em;border-bottom:1px solid #e0e0e0;padding:1em 0;\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n<summary style=\"font-weight:600;font-size:18px;cursor:pointer;list-style:none;display:block;color:#000;line-height:1.6;position:relative;padding-right:40px;\" itemprop=\"name\">Do I need liver function tests before starting Wegovy?<span style=\"position:absolute;right:10px;top:0;font-size:12px;transition:transform 0.3s;\" class=\"faq-arrow\">\u25bc<\/span><\/summary>\n<div style=\"margin-top:0px;padding-top:0px;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size:18px;line-height:1.8;color:#333;margin:0;\" itemprop=\"text\">Yes, baseline liver function tests (ALT, AST, GGT, bilirubin) are standard protocol before starting Wegovy. Most prescribers repeat these tests at 12 weeks and 24 weeks to track hepatic response, especially in patients with metabolic syndrome or known fatty liver. The goal isn&#8217;t to screen for toxicity \u2014 semaglutide doesn&#8217;t cause liver damage \u2014 but to document baseline enzyme levels and monitor the expected improvement as liver fat clears.

Decompensated cirrhosis (Child-Pugh Class B or C) is a relative contraindication; the rapid metabolic shifts GLP-1 agonists trigger may overwhelm compromised hepatic function.

Wegovy treats both \u2014 it reduces liver fat by 30\u201340% in NAFLD patients and resolves steatohepatitis in 59% of NASH patients according to biopsy-confirmed trials.

MRI-PDFF imaging from the STEP trials showed that intrahepatic triglyceride content dropped from baseline averages of 15\u201318% down to 8\u201310% by week 48. Most patients see normalisation of liver enzymes (ALT, AST) within 16\u201320 weeks, which correlates with hepatic fat clearance.

Cholelithiasis (gallstones) and cholecystitis (gallbladder inflammation) can elevate liver enzymes (ALT, AST) secondarily by obstructing bile flow or causing localised inflammation near the liver. If liver enzymes rise during Wegovy treatment, abdominal ultrasound to evaluate the gallbladder is the first diagnostic step. Gallbladder-related enzyme elevation is mechanistically distinct from drug-induced liver injury and resolves with cholecystectomy if surgery is required.<\/p>\n<\/div>\n<\/details>\n<details class=\"faq-item\" style=\"margin-bottom:1em;border-bottom:1px solid #e0e0e0;padding:1em 0;\" itemscope itemprop=\"mainEntity\" itemtype=\"https:\/\/schema.org\/Question\">\n<summary style=\"font-weight:600;font-size:18px;cursor:pointer;list-style:none;display:block;color:#000;line-height:1.6;position:relative;padding-right:40px;\" itemprop=\"name\">Will my liver improve if I stop taking Wegovy?<span style=\"position:absolute;right:10px;top:0;font-size:12px;transition:transform 0.3s;\" class=\"faq-arrow\">\u25bc<\/span><\/summary>\n<div style=\"margin-top:0px;padding-top:0px;\" itemscope itemprop=\"acceptedAnswer\" itemtype=\"https:\/\/schema.org\/Answer\">\n<p style=\"font-size:18px;line-height:1.8;color:#333;margin:0;\" itemprop=\"text\">Liver fat reduction achieved on Wegovy is not permanent if the medication is discontinued. The STEP extension trials showed that patients who stopped semaglutide after 68 weeks experienced gradual reaccumulation of hepatic fat over the following year, though levels did not return fully to baseline. The metabolic benefits \u2014 reduced lipogenesis, improved insulin sensitivity \u2014 depend on continuous GLP-1 receptor activation.

Hepatic fibrosis (scarring) takes years to remodel, and current trial durations (68\u2013104 weeks) may be too short to capture full structural reversal. Observational data suggests that patients with F2 or F3 fibrosis at baseline who remain on therapeutic-dose semaglutide for 18\u201324 months see modest improvements in FibroScan scores (kPa readings), but advanced fibrosis (F4\/cirrhosis) is unlikely to reverse fully.
