Birth Control
Oral contraceptives function by altering hormone levels, preventing ovulation and egg release from the ovaries. In turn, this stops the patient from becoming pregnant.
Anything that alters hormone levels might also influence the biliary system, which includes the liver and gallbladder. If the food is not digested regularly, it is more likely to have green stools. Diarrhea induced by birth control methods impairs the body’s ability to absorb nutrients, drinks, and medicines. Instead of being absorbed into the circulation, they are eliminated by feces.
Green feces have been reported as a side effect of Depo-Provera (medroxyprogesterone). The Depo-Provera injection suppresses ovulation and has been linked to bloating or weight gain in some women. There have been patients experiencing green feces most often after the first few doses. This is because it encourages the secretion of more bile. Other drugs may cause distinct color changes. For instance, Pepto Bismol and iron supplements might briefly tint feces green. If you suspect your green stools are not due to your diet, plan an appointment with your doctor to discuss your concerns.
