What vitamin deficiency causes constipation?

      Constipation may be associated with deficiencies in certain vitamins in the body, such as vitamin B12, vitamin C, and vitamin D.

      1. Vitamin B12

        Vitamin B12 is an essential nutrient for the human body and plays an important role in regulating nerve function in the stomach, intestines, and other areas. Long-term deficiency of this substance can slow gastrointestinal motility and trigger or worsen constipation.

      2. Vitamin C

      Vitamin C is beneficial for promoting metabolism in tissues such as the stomach and intestines and enhancing immune function. Prolonged insufficient intake of vitamin C can impair the normal functioning of gastric and intestinal tissues, leading to symptoms such as bloating and constipation.

      3. Vitamin D

      Vitamin D helps regulate the balance of salt compounds such as phosphorus, calcium, and potassium in the body's bloodstream. A deficiency in this vitamin can impair the normal contraction and relaxation functions of smooth muscles in organs such as the stomach and intestines, resulting in chronic constipation, dry and hardened stools, and similar conditions.

      Constipation may also be related to deficiencies in vitamin D and other vitamins. It is recommended that patients undergo a series of medical examinations at a hospital to determine the exact cause and then follow medical advice for standardized treatment.
