What is Wegovy® and How Does It Work?

Wegovy® is an injectable prescription medication containing semaglutide, which is classified as a glucagon-like peptide-1 (GLP-1) receptor agonist. It works by mimicking the effects of the incretin hormones that the body produces naturally to regulate appetite and food intake. This medication helps individuals feel fuller for longer periods, which can lead to reduced caloric intake and subsequent weight loss.

Wegovy® is typically prescribed for adults and children aged 12 years and older who are classified as obese or overweight and have weight-related health conditions, such as high blood pressure or type 2 diabetes. In conjunction with a reduced-calorie diet and increased physical activity, Wegovy® aims to achieve long-term weight management.

Common Side Effects of Wegovy®

As with any medication, side effects can vary widely among individuals. Here are some of the most commonly reported side effects associated with Wegovy®:

1. Nausea

Nausea is perhaps the most frequently reported side effect, affecting approximately 44% of patients. This gastrointestinal issue can range from mild to moderate in severity and often occurs at the beginning of treatment or following a dose increase.

Management Tips:

  • Eat bland, low-fat foods like crackers or toast to help settle your stomach.
  • Stay upright after meals to minimize discomfort.
  • Gradually increase your food intake to allow your body to adjust.

2. Diarrhea

Around 30% of users may experience diarrhea, which can also be distressing. This side effect is generally temporary and tends to improve as your body adapts to the medication.

Management Tips:

  • Stay hydrated by drinking plenty of water, especially if diarrhea persists.
  • Consider consuming foods that are easy on the stomach, such as bananas, rice, or applesauce.

3. Vomiting

Vomiting can occur in approximately 24% of users, making it another common side effect. Like nausea and diarrhea, it is usually mild and resolves over time.

Management Tips:

  • If vomiting occurs, rest and hydrate to prevent dehydration.
  • Avoid large meals and opt for smaller, more frequent meals.

4. Constipation

Some individuals may experience constipation, with about 24% reporting this side effect. It may occur due to changes in gastrointestinal motility caused by the medication.

Management Tips:

  • Increase fiber intake through fruits, vegetables, and whole grains.
  • Drink plenty of fluids and consider gentle physical activity to stimulate bowel movements.

5. Abdominal Pain

About 20% of Wegovy® users report abdominal pain. This discomfort can vary in intensity and may be related to other gastrointestinal side effects.

Management Tips:

  • Monitor your diet and identify any foods that may trigger discomfort.
  • Speak with your healthcare provider if the pain persists or worsens.

6. Fatigue

Fatigue is another side effect experienced by some users, potentially due to the body adjusting to the medication or changes in dietary habits.

Management Tips:

  • Ensure you are getting adequate rest and nutrition.
  • Engage in light physical activity to boost energy levels.

7. Dizziness

Dizziness can affect a smaller percentage of users, and it may be linked to changes in appetite or caloric intake.

Management Tips:

  • Avoid sudden movements and ensure you are well-hydrated.
  • If dizziness persists, consult your healthcare provider.

8. Feeling Bloated and Belching

These symptoms, affecting around 6% of users, can be uncomfortable. They often relate to the medication’s effects on digestion.

Management Tips:

  • Eat smaller meals and chew food thoroughly to aid digestion.
  • Avoid carbonated beverages that may exacerbate bloating.

Serious Side Effects of Wegovy®

While many side effects of Wegovy® are manageable, it’s essential to be aware of more serious, albeit rare, risks associated with the medication. These include:

1. Thyroid Tumors

Wegovy® carries a warning regarding the potential risk of thyroid tumors, including medullary thyroid carcinoma (MTC). This association has been observed in animal studies, but it remains unclear if the risk extends to humans.

Important Actions:

  • Inform your healthcare provider if you have a family history of MTC or multiple endocrine neoplasia syndrome type 2 (MEN 2).
  • Monitor for symptoms such as a lump in the neck, changes in voice, or difficulty swallowing.

2. Pancreatitis

Wegovy® may increase the risk of pancreatitis, which is an inflammation of the pancreas. Symptoms can include severe abdominal pain, vomiting, and nausea.

Important Actions:

  • Seek immediate medical attention if you experience severe abdominal pain that radiates to your back.
  • Discuss any history of pancreatitis with your healthcare provider.

3. Gallbladder Problems

Gallbladder issues, including gallstones, have been reported in some users of Wegovy®. Symptoms can range from discomfort to severe pain.

Important Actions:

  • Inform your healthcare provider of any history of gallbladder problems.
  • Monitor for symptoms such as sudden abdominal pain, nausea, or jaundice (yellowing of the skin or eyes).

4. Low Blood Sugar (Hypoglycemia)

Wegovy® can lead to low blood sugar levels, particularly in individuals taking insulin or other diabetes medications. Symptoms may include dizziness, sweating, and confusion.

Important Actions:

  • Be aware of the signs of low blood sugar and keep glucose tablets or juice on hand.
  • Discuss your diabetes medications with your healthcare provider to ensure proper management.

5. Allergic Reactions

Severe allergic reactions, including anaphylaxis, have been reported in some cases. Symptoms may include swelling, rash, or difficulty breathing.

Important Actions:

  • Seek emergency medical assistance if you experience any signs of a severe allergic reaction.
