Yes it can, as the stomach is a muscle, fibromyalgia is a deterioration of muscles. My friend tries to walk as much as possible to make her muscles stronger, and has eliminated a lot of different food from her diet that caused stomach upset
Fibromyalgia is caused by a multitude of medical issues and IBS is one. God Bless
Fibromyalgia is characterized by widespread pain and fatigue. Exact etiology of this condition is not known. Symptoms of Fibromyalgia can be treated with medicines and changes in lifestyle. Its symptoms are widespread pain, fatigue, sleep disturbances, constipation, diarrhea, bloating and abdominal pain. So, Fibromyalgia can cause stomach problems.
There are many health problems that tend to accompany Fibromyalgia. One of them is Irritable Bowel Syndrome (IBS). The symptoms of this can fluctuate from constipation to diarrhea, and can also include bloating and stomach pains. Even if this is part of your Fibromyalgia, you need to see a Gastroenterologist to have this seen about. You can change your diet to help relieve some of the symptoms. There are also medications now that can help the symptoms of IBS. One example is Amitiza which is for IBS-C (CONSTIPATION). If you are in pain, you can get some relief. I have been there. God Bless!
