Is chronic diarrhea common 20 years after gastric bypass surgery?

Question

Fady Moustarah, MD · Answer

Bowel movements usually change after weight loss surgery. After a gastric bypass one can expect more frequent bowel movements. The intestines do adapt over time, but 20 years out, you should not be having "chronic diarrhea." Chronic diarrhea is defined as loose stools that last for at least four weeks. This usually means three or more loose stools per day. Other causes or contributing factors should be considered to help diagnose the reason for your diarrhea if it meets clinical criteria for being worrisome. This symptom should not be ignored as it could make it difficult for you to maintain good nutritional health in the context of your bypass surgery, which alone requires long term follow-up, proper nutrition, and vitamin supplementation. If you have not seen your physician to review your health from a gastric bypass perspective in over 1 year, now is a good time to call your doctor's office or see a bariatric surgeon or physician for an evaluation.

Chronic diarrhea is not typically expected 20 years after gastric bypass surgery, but it can occur in some individuals due to various reasons. While gastric bypass is an effective procedure for weight loss, it alters the digestive system significantly, and some long-term effects may develop over time.
One possible cause of chronic diarrhea could be dumping syndrome, a condition where food, especially sugary or fatty foods, moves too quickly from the stomach to the small intestine. Although this is more common in the early years after surgery, some individuals may experience it long-term if their diet includes foods that trigger this response.
Another potential factor is bacterial overgrowth in the small intestine, which can sometimes develop due to changes in the digestive tract after bypass surgery. This can lead to diarrhea, bloating, and discomfort. Additionally, malabsorption of nutrients, particularly fats, might result in loose stools, especially if dietary adjustments or supplements are not managed well.
Food intolerances or sensitivity to certain ingredients like lactose can also contribute to chronic diarrhea. Over time, your digestive system may respond differently to foods you previously tolerated.
While chronic diarrhea is not a common or expected outcome two decades after gastric bypass surgery, it is not unheard of and should be evaluated to ensure your digestive health is optimized.

Chronic diarrhea is a potential long-term complication after gastric bypass surgery, but it is not considered common for individuals to experience this symptom 20 years after the procedure. The prevalence and severity of side effects can vary among patients, and while many people benefit from significant and sustained weight loss after gastric bypass surgery, some may experience gastrointestinal issues.

Hello, I hope you are well. A gastric bypass causes a certain degree of malabsoprtion which in turn can cause diahrrea. However, if you are experiencing a difference in your regular bowel patterns, you need to be evaluated by your bariatric surgeon or your PCP, as there are several reasons that can be attributed to diarrhea, including a parasitic infection.

Ariel Ortiz, MD, FACS · Answer

No it is not common, but also not unheard-of,.
 Diarrhea  after gastric bypass can be caused  by a form of dumping  syndrome, malabsorption of certain  foods or nutrients, food intolerance,  concentrated  beverages can generate osmotic  diarrhea, bacterial over growth in the biliopancreatic limb, or other causes not related to the bypass. You have to check with your bariatric surgeon or GI specialist  to establish the cause and receive the proper treatment .
