Gallbladder health on treatment: tummy pain, gallstones and when to call

The gallbladder is a small, pear-shaped organ on the right side of the upper tummy, below the liver. It stores bile from the liver and makes it more concentrated. Bile helps the gut digest fat. When some of the substances in bile clump together, gallstones can form (gesundheitsinformation.de).

Many people have gallstones without knowing it. If they cause no symptoms, they usually need no treatment (NHS; gesundheitsinformation.de).

The product information for weight-management medicines used as a weekly injection or daily tablet names gallbladder problems, including gallstones, as possible side effects (EMA product information). The German health information service of IQWiG also lists certain medicines of this kind among the risk factors for gallstones (gesundheitsinformation.de).

Other things that make gallstones more likely include being over 40, being a woman, living with obesity, a diet high in fat and low in fibre, losing a lot of weight in a short time, for example after weight-loss surgery, and diabetes (NHS; gesundheitsinformation.de). Pregnancy, the contraceptive pill or oestrogen tablets and gallstones in the family also raise the risk (gesundheitsinformation.de).

This is not a reason to worry, but a reason to know the signs and tell your doctor early.

Gallstone pain can feel severe and constant, last longer than 30 minutes and up to several hours, sit in the middle of your tummy or just under the ribs on the right side, and make you feel or be sick (NHS). It can come in waves and spread to your back and right shoulder (gesundheitsinformation.de).

Some people also notice a feeling of fullness, wind, diarrhoea, heartburn or nausea (gesundheitsinformation.de). If a stone blocks a bile duct, it can cause jaundice: yellow skin or yellow whites of the eyes, itchy skin, darker pee and paler poo than usual. Yellow skin may be less easy to see on brown or black skin (NHS).

The product information also asks you to see a doctor straight away if you have severe tummy pain that does not go away, as this can be a sign of an inflamed pancreas (EMA product information). Gallstones can also lead to inflammation of the gallbladder or the pancreas (NHS).

Whether particular habits prevent gallstones has not been well studied. A healthy lifestyle with regular physical activity and balanced eating may still help lower the risk (gesundheitsinformation.de).

Build meals around vegetables, fruit, wholegrains and pulses, which bring fibre, and keep very fatty meals the exception (NHS; DGE). Drink enough, mainly water or unsweetened tea (DGE). With a quieter appetite, smaller, regular meals eaten slowly may feel more comfortable.

Do not change, pause or stop your treatment on your own. Talk to your prescribing doctor first.

Ask for a prompt appointment with your GP or contact your prescribing doctor if you have tummy pain that lasts longer than 30 minutes (NHS). Outside surgery hours, call the medical on-call service on 116117 (116117.de).

Call 112 if you have sudden, severe tummy pain, pain that spreads from your tummy to your back while you are being sick, a very high temperature or feel hot, cold or shivery, or if your skin or the whites of your eyes look yellow (NHS; gesund.bund.de). The 112 call is free and available day and night (gesund.bund.de).

Do not drive yourself to hospital. Ask someone to drive you or call an ambulance, and bring the medicines you take (NHS).

Mention earlier gallstones, gallbladder inflammation or a removed gallbladder in your questionnaire, and tell your prescribing doctor about any new tummy pain, yellowing of the skin or eyes, or other changes (EMA product information). Your doctor decides with you what happens next.

A doctor reviews your information and decides on the prescription. You can report suspected side effects in Germany through the BfArM and PEI reporting portal.
