<s>[INST] Hi, my name is Marie, I have been having these symptoms for quite a while and no one seems to know the answer. I will get the erge to have a bowel movement and then once in the bathroom the erge turns into severe abdomnal cramps, my heart starts to pound, I feel lightheaded, break out in a cold sweat and become very weak. When all starts to disapate I`ve had a large loose movement and I am so weak and lightheaded that I can hardly walk the 10 feet to my bed only to colapse and sleep for about an hour or so. For several days after my sbdomanal muscles are sore and I am very weak. I am 65.7 yrs. old. Thank You for any help or advise tyou can give. [/INST] HI Marie Madam.The urge- ramps- weakness, sweats and associated symptoms- large loose motion - very weak- all are suggestive of the following. Severe form of Entero-colitis. In this the symptoms are classical as you have. I would advise :::To get admittedComplete investigations including that for diabetes , kidney function tests.Stool tests Ultrasonography of abdomen Intravenous fluids and antibiotics.Colonoscopy, biopsy.CT scan abdomen if required. You have to get treated and investigated simultaneously so that you are cured. </s>
