Ramadan fasting means no food and no water from dawn until sunset, for a month. Many people taking Ozempic or another GLP-1 want to fast, and many do so safely. But fasting on these medications is different from fasting without them, and it is worth planning with your clinician before the month begins rather than discovering the problems on day three.<\/p>\n
Whether to fast is a personal and religious decision. Islamic teaching includes exemptions for people who are unwell, and many people find it helpful to talk with both their clinician and a religious leader they trust. This article covers the medical and practical side.<\/p>\n
Three things change.<\/p>\n
Dehydration risk is higher.<\/strong> No water during daylight hours is already demanding, especially when Ramadan falls in warmer months. These medications can cause nausea, vomiting, and diarrhea, and people on them often drink less and get less fluid from food. Dehydration from gastrointestinal side effects has been linked to kidney problems with this class of medication.<\/p>\n Eating enough in a short window is harder.<\/strong> You have only the hours between iftar and suhoor to eat everything for the day, on a medication that makes you full quickly. Many people end up eating far less than they intended.<\/p>\n Low blood sugar is a real concern for some people.<\/strong> The prescribing information for Wegovy, which contains semaglutide, the same active ingredient as Ozempic, notes that patients with diabetes mellitus taking it in combination with insulin or an insulin secretagogue, such as a sulfonylurea, may have an increased risk of hypoglycemia, including severe hypoglycemia. Long daytime fasts add to that risk. If you have diabetes and take any of those medications, a conversation with your clinician before Ramadan is essential, because the doses or timing of those medications may need to change.<\/p>\n A few weeks before the month starts, ask your provider:<\/p>\n Do not step up your dose just before or during Ramadan.<\/strong> Ask your provider to schedule any increase for after Eid. Our guide on dose escalation<\/a> covers how the steps usually work.<\/p>\n If you are thinking of starting Ozempic,<\/strong> the first weeks are when side effects tend to be strongest. Starting right before Ramadan is usually not ideal. Our guide on the Ozempic starting dose<\/a> covers what the early weeks involve.<\/p>\n Do not stop your medication on your own for the month<\/strong> without discussing it. Restarting after several weeks off can bring back strong side effects, and it usually means stepping back down rather than resuming where you were. Our guide on taking a break and restarting<\/a> covers why.<\/p>\n Suhoor has to carry you through the whole day, and on a small appetite it is tempting to skip it. Try not to.<\/p>\n Eat suhoor as late as you can<\/strong> before dawn.<\/p>\n Include protein,<\/strong> such as eggs, yogurt, cheese, beans, or leftover meat or chicken.<\/p>\n Choose slow foods<\/strong> like oats, whole grains, and fruit rather than very sweet or very salty foods, which can make thirst harder during the day.<\/p>\n Drink steadily,<\/strong> spreading water through the hours between iftar and suhoor rather than drinking a large amount at once, which can be uncomfortable on a slow stomach.<\/p>\n After a long fast, the instinct is to eat a lot quickly. On these medications, a large, rich, fried iftar eaten fast is the most common cause of nausea and discomfort during Ramadan.<\/p>\n Break your fast with water and dates,<\/strong> as many people traditionally do, then pause before the main meal.<\/p>\n Start the meal with soup or protein,<\/strong> and eat slowly.<\/p>\n Go easy on fried foods<\/strong> such as samosas and pakoras, and very sweet desserts.<\/p>\n Spread food across the evening<\/strong> if you cannot manage a full meal at iftar. A second small meal later in the evening can help you get enough.<\/p>\n These are signs to break your fast and contact your clinician, whatever the hour:<\/p>\n Breaking the fast for your health is consistent with the exemptions in Islamic teaching, and many people make up missed days later.<\/p>\n Consider this scenario: someone on Ozempic who also takes a sulfonylurea for type 2 diabetes begins fasting without talking to their clinician. They skip suhoor because they are not hungry, and in the afternoon of the third day they become shaky, sweaty, and confused. A conversation before Ramadan about their diabetes medication, a proper suhoor with protein, and knowing the signs to break the fast would have prevented that afternoon.<\/p>\n Eid al-Fitr brings celebration, visits, and sweets after a month of fasting. Your stomach may not be ready for a large feast straight away. Eat slowly, take small portions of what you most enjoy, and keep drinking water. Our guide on getting the most out of your GLP-1 treatment<\/a> covers the everyday habits worth returning to after the month.<\/p>\n Talk to your provider weeks before Ramadan about whether to fast, your dose, your injection timing, and your other medications, especially if you have diabetes. Do not step up your dose or stop on your own around Ramadan. Never skip suhoor, include protein, and drink steadily overnight. Break your fast gently with water and dates and eat slowly. Know the signs that mean you should break your fast, and take them seriously.<\/p>\nBefore Ramadan: talk to your provider<\/h2>\n
