Hi, I noted the history of getting abdominal cramps on waking up in the morning, feel like gong to have diarrhea, sweats horribly on sitting on the toilet, feel dizzy like going to faint and feel nausea, feel better for a few minutes and it is all back. This is classically seen in cases of Proctocolitis, IBS and when the autonomous nervous system is at its height. You have got the symptoms related to severe form of the vagal overtone due to underlying colitis. I would advise you the following: - Get the stool tested for 3 consecutive days. - Tests of blood and urine. - Ultrasonography. Get an appointment for colonoscopy and CT scan of the abdomen. Once diagnosed the treatment becomes easy and may be as follows. Antibiotic cover if there is an evidence of infection, Probiotic, Symptomatic, Anti-spasmodic and so on as per the clinical evaluation and reports of investigations. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. T Chandrakant
