[|Human|] I frequently feel dizzy and neasous after short periods of excercise or even for no apparent reason. My feet sometimes tingle. I am always sleepy and can hardly stay awke for 8 hours at a time. I have recently started eating more than usual and I am constantly hungry even after eating large meals. Is there something wrong?
[|AI|]  Hello, Dizziness, nausea, tingling sensation in feet and increased appetite are suggestive of impaired glucose metabolism or even diabetes mellitus. I suggest you get blood glucose levels fasting and postprandial. Fasting glucose levels below 100 mg/DL are normal, between 100-125 suggests impaired glucose tolerance and above 126 mg/DL suggests diabetes mellitus. Postprandial glucose levels (after two hours of having food) below 140 mg/DL is normal, between 141-200 mg/DL is indicative of impaired glucose tolerance and above 200 mg/DL is suggestive of diabetes mellitus. If the test results are abnormal appropriate treatment can be started, and thus the symptoms will relieve. Hope I have answered your query. Let me know if I can assist you further.
