I went to the hospital for an examination of my large intestine yesterday. I drank a washing liquid like a sports drink for about 2 liters. It was too much for me. After drinking, I took a walk to clean my stomach. I had diarrhea many times. The nurse checked my excrement. She said the transparency is ok. The doctor checked my stomach using an endoscope. It hurts. I've been stressed recently, the doctor said this might be the reason why my bowel movement is affected. The doctor took my bowel's tissue. The result will be given next year. I am afraid that it's cancer. The doctor said it's not cancer. I said "really?" and the doctor told me not to worry. I asked the doctor that if it's not cancer then why are you taking my bowel's tissue? The doctor told me that my bowel is irrirated.
