DEAR DOCTOR K: I suffer from constipation. Do you think probiotics might help?
DEAR READER: Probiotics are living bacteria found in cultured foods, like yogurt, and in dietary supplements. They have long been touted for their ability to ease digestive woes. The strongest evidence for probiotics is in treating diarrhea caused by a viral infection or from taking antibiotics. Our bodies are home to a mix of "good" and "bad" bacteria.
