Depression is not necessarily related to diarrhea. If diarrhea occurs recently, you can drink some salt water to replenish the lost electrolytes and prevent symptoms such as dizziness, weakness and muscle aches due to electrolyte disturbance in the body. Generally, diarrhea will heal itself soon after taking good rest and eating lightly. If the diarrhea is serious, you can take some antidiarrheal drugs such as montelukast to relieve the symptoms. If the symptoms are severe and difficult to relieve for a long time, it is recommended to go to the hospital to check the cause of diarrhea, and then carry out symptomatic treatment. Patients with depression usually have a chronic low mood, extremely low self-esteem, little interest in anything or anyone, and a significant decrease in memory and concentration. If you suspect that you may be suffering from depression in the context of your recent condition, you should go to the psychiatry department of a regular hospital as soon as possible to get advice and help from a professional doctor.
