How to use weight loss medications during Ramadan safely

Avoid increasing dosage

Dr Verma recommends avoiding altering your medication dosage during Ramadan, as side effects can become most pronounced when increasing this. She said: “Some of the side effects of weight loss treatment, such as vomiting or diarrhoea, increase the risk of dehydration and can be more challenging to deal with if you’re fasting.”

Consider medication timings

When you are taking your treatment, consider timing it just before breaking your fast, as the effects won’t be felt until after you’ve had time to eat. Dr Verma said: “This allows you to have a more substantial meal and get vital nutrients on board before the appetite suppression kicks in.”

Prioritise nutrient-dense meals

When breaking your fast pre-dawn, try to include slow-release energy foods on your plate, such as oats, wholegrain bread or brown rice and aim to fill half your plate with vegetables to get enough vitamins and minerals. Dr Verma said: “Many Muslims traditionally open their fast by eating dates with water before a meal, which is a great source of fibre and energy from the natural sugars they contain.”

Remember portion sizes

Weight loss treatments slow digestion, so avoid large, heavy meals and pay attention to the amount of food you eat at Suhoor and Iftar. Dr Verma said: “Keeping fried, oily and sugary foods to a minimum will help maintain balance in nutrition and reduce chances of side effects.”

Stay hydrated

When permitted, make sure you drink lots of water and include fluid-rich foods such as yoghurt, soup, cucumber and watermelon to help you stay hydrated. Dr Verma said: “Some people may opt to take electrolytes to help replenish essential minerals lost during fasting and to aid overall hydration.”

Ensure extra time to rest

One of the hardest things to deal with is the lack of sleep after waking for pre-dawn meals and prayers. Dr Verma recommends a 30 to 40-minute power snooze at lunch to help refresh you. Any longer than 40 minutes, and you may go into a deep sleep and wake up feeling groggy.

Managing side effects

If you experience side effects such as severe nausea or dehydration during fasting, Dr Verma recommends you consult with your clinician about lowering your dose. She said: “In some cases, temporarily pausing the treatment may be required. But many of our Muslim patients are able to continue with weight loss treatment throughout Ramadan by making sensible adjustments.”
