Why am I weak and shaky sometimes?

50-70 is low blood sugar. Try to take some snacks along to eat before or as you are starting to feel like this. Foods and beverages that contain carbs have the biggest effect on blood sugar. The higher on the glycemic index, the more they raise your blood sugar.

High: 70 and up. Examples include instant white rice, brown rice, plain white bread, white skinless baked potato, boiled red potatoes with skin and watermelon.

Medium: 56 to 69. Examples include sweet corn, bananas, raw pineapple, raisins and certain types of ice cream.

Low: 55 and under. Examples include raw carrots, peanuts, raw apple, grapefruit, peas, skim milk, kidney beans and lentils.

Here is a list of the glycemic index of many common foods...

Does your breakfast include animal protein sources? (good)

Carbs like prepared breakfast cereals (bad) and toast (bad), especially if *just* carbs.

Orange juice? (fructose - sugar - bad). Orange juice will sometimes do that due to high potassium and high sugar content.

If you have a good animal protein and animal fat sources in the morning, your blood sugar will be moderate throughout the day with small spikes when you consume something. If you eat a high carb breakfast, your blood sugar spikes and drops and spikes and drops each time you consume something, also leading to urges for sugary snacks to get through the afternoon.

Could also be due to B-vitamin lack or malabsorbtion which could be caused by either meds you are on (check the web for nutrition deficiencies caused by specific meds, or classes of meds) or your colitis. Most B-vitamins are essentially 'produced' in the gut by our healthy gut flora and animal protein/fat.

I am not a doctor but I think you need to have your blood sugar checked. I've had similar experiences.

I too am diabetic.a good breakfast and a correct breakfast are two different worlds.smaller and more frequent meals helps.oatmeal and yogurt for breakfast. That should powerpower you up. a strong multi vitamin will help too.
