Why weight loss causes constipation

Weight loss can lead to constipation due to low water intake, low fiber diet, low food intake, etc.

Usually, stool needs a certain amount of water to be able to pass smoothly out of the intestine. If the patient drinks less water during weight loss, it may lead to excessive drying of stool and constipation. If the patient eats less or does not eat foods containing fiber during weight loss, it will usually lead to slow bowel movement and constipation. Some people who lose weight may achieve their goals through dieting. In this case, stool loss may occur due to less food in the gastrointestinal tract.
