Diabetes does not often cause headaches. The headaches are not usually dangerous in themselves. However, they may indicate problems with blood sugar control in a person with diabetes.
Depending on whether your blood sugar is too low or too high, diabetes-related headaches can cause other symptoms too:
- Low blood sugar headache can leave you feeling shaky, faint, nauseous, or sweaty.
- High blood sugar headache may be accompanied by feeling super thirsty or having to pee more than usual, fatigue, or blurred vision
Both hypo- and hyperglycemia can trigger headache and migraines. They can be super painful, with a throbbing or pulsing sensation on in your head. You might also feel weak, sensitive to light or sound and nauseous.
This is what I do to I keep it from coming back:
Manage my blood sugar level
I check my levels frequently, up to several times a day. I aim to keep my blood sugar between 4.4 mmol/L and 7.2 mmol/L before meals and below 110.0 mmol/L, 2 hours after meals.
Food plays a major role in hyper- or hypoglycemia. Fill your plate with foods that can help control your blood sugar, like meat, vegetables, fruits, grains, protein, dairy—nonfat or low fat.
Drink enough water
Dehydration is a top cause of headache in general, so making sure that you’re drinking enough.
To conclude, the first step to preventing more severe health problems will be to recognize that the headache is a result of poor blood sugar control. That’s why it’s important to manage your diabetes well and keep your blood sugar levels under control. By doing all of this, you are less likely to experience headaches. But keep in mind the following. If headaches are severe but your blood sugar levels are under control, you should go to ask your doctor for further advice.
