Undiagnosed medical conditions

A huge range of health conditions can cause constipation, Dr. Iqbal says. The most common one he sees, particularly in younger people, is hypothyroidism. “Your thyroid controls your metabolism so when it’s not functioning well, everything slows down, including your gut,” he explains. Other illnesses that have constipation as a major symptom include diabetes, multiple sclerosis, inflammatory bowel disease, Celiac disease, autoimmune disorders, and some cancers.
