Dry stool is not a good sign. Dry stools are mostly due to the fact that the water content is relatively low and there is no residue when the stool passes through the anus. This condition can be caused by drinking less water in general, or eating too much dry and hot food and lack of exercise. Dry stools can also be seen in pathological conditions such as diabetes and hypothyroidism. There is no pathological disease of dry stool patients, usually in the diet can eat some rich in dietary fiber fruits and vegetables and coarse grains, mixed grains. Appropriate exercise, such as running and walking, can accelerate the peristalsis of the gastrointestinal tract, which has a certain effect on the improvement of dry stools. In addition, patients should also develop the habit of regular defecation, which can improve constipation. Dry stools caused by underlying diseases need to be treated for the underlying diseases and at the same time give symptomatic treatment for dry stools. Patients with severe constipation are advised to consult a doctor in time and follow the doctor’s instructions for treatment.
