Drinking tea for a long time may lead to constipation, especially strong tea. 1. Because tea contains caffeine, it will have an excitatory effect on the heart and other organs, but has an inhibitory effect on the gastrointestinal tract and so on. Therefore, it may slow down the gastrointestinal tract peristalsis, resulting in constipation. 2. Tea also contains ellagic acid, if you eat high protein food when drinking tea, ellagic acid and protein will react, not conducive to digestion and absorption, which in turn leads to constipation. It is recommended that patients eat more fresh fruits and vegetables in daily life, such as bananas, spinach, etc., in order to supplement dietary fiber, and also appropriate physical exercise to promote gastrointestinal peristalsis. If the patient’s constipation symptoms are serious, or continue to see no improvement, it is recommended to go to the regular hospital in time, under the guidance of the doctor for targeted treatment.
