Taking Medications and Vitamin Supplements

Taking medications

  • With the exception of NSAIDs (see below), the general advice is to continue to take prescribed medication but please refer to the advice given to you by our medical team. If you are in any doubt, please call a bariatric nurse on 0121 693 4488.

  • If your tablets are large, some medications may need to be crushed or taken in liquid form for the first six weeks after your surgery. Please check with your doctor whether your medication is available in a liquid or soluble preparation. Seek medical advice before crushing your pills as many common medications are slow-released and cannot be crushed

  • If you take medication for diabetes, please check with your doctor before restarting medication after your procedure as your requirements are likely to be much less than they were prior to your surgery

  • Medications that irritate the stomach should be avoided, especially non-steroidal anti-inflammatory medicines such as aspirin, Ibuprofen, Diclofenac, Sulindac, Celecoxib, Diflunisal, Naproxen, Piroxicam etc. If you are unsure, call to speak to a nurse 

Vitamin and Mineral Supplements

Vitamins and minerals are vital for appetite regulation, fat storage and metabolic rate so are important for good health, weight loss and long term weight maintenance. After weight loss surgery, portion sizes are smaller, some food groups may not be tolerated and there may be reduced absorption of vitamins and minerals. It is, therefore, essential for all sleeve / ESG patients to take multi-vitamins for life. Failure to do so may lead to health problems. Our Bariatric Nurse will discuss this with you during your pre-operative call. You need to start taking vitamins at week 3 and we recommend that you take each of the following supplements daily:

If you are deficient, intramuscular injections of 1mg vitamin B12 every three months will be required. You may wish to have your B12 level checked by your GP on an ongoing basis. Your GP will advise but this is likely to be once or twice a year.
