Guide To The Side Effects Of Metformin

Diarrhea Or Constipation

Patients may experience stool changes such as diarrhea or constipation while taking metformin. Diarrhea affects around fifty-three percent of patients on metformin, and constipation is less common. Diarrhea occurs when the patient has loose, watery stools three or more times in twenty-four hours, and stomach cramps may be present. To reduce diarrhea, it may help to consume low-fiber foods and avoid dairy products and high-fat foods. Most cases of diarrhea related to metformin use are self-limiting and resolve without treatment; however, patients may wish to use an over-the-counter medication such as loperamide or bismuth subsalicylate to treat diarrhea at home. A physician should be consulted if diarrhea persists or if black stools occur as these may be a sign of a more serious condition.

Constipation develops if patients have stools that are dry, hard, or difficult to pass, and most doctors define constipation as having fewer than three bowel movements per week. Patients with constipation could experience pain during bowel movements, and there may be a constant sensation of fullness in the rectum. To treat constipation, doctors recommend that individuals increase their dietary fiber intake, and it may be necessary to take over-the-counter laxatives. Severe constipation may require an enema, and surgery is necessary if untreated constipation leads to a bowel blockage. Patients who take metformin should check with their doctor about whether they need to take fiber supplements or other medicines to prevent constipation.
