I have type two diabetes. Insulin short acting with meals. Long acting morning and evening. Successfully lowered A1c to 6.2 and have established training sessions four 45 minutes a week minimum. Problem is lunch time low blood sugar in 50s this past week with episode of itchy arms. Was going to call my doc Monday. Today very alarming......took count was 115....injected 20 fast acting....ate lunch.....one tablespoon peanut butter on wheat bread, one slice water melon 3 oz and banana......bottled water..... Fifteen minutes later went to a store felt very sweaty, sat in cafe took blood sugar, shaky, was 48.....had to drink 12 oz of regular soda to raise to 69......and my body odor was horrible from episode....this was all new to me. I also noticed my arm is black and blue and other arm got welts and rash that disappeared once blood sugar came up to 110. I will call my doc tomorrow but wonder if I should take my slow acting insulin tonight. My last reading was 110.
