Hello doctor, My 47-year-old father's blood sugars are fluctuating. A month ago he was not taking any medication and was not performing any exercise. At that time, his sugars were around 380. Now he is doing some yoga and playing volleyball. Suddenly, his sugars decreased a lot to around 100. Our family doctor suggested that this would have happened because he was not eating on time. The last couple of days he was suffering from low sugar which is causing him vertigo and sweating. Please help.
Hello. I understand your concern.  You have not mentioned if your father is currently taking any medication for blood sugar control. If he is still not taking any medication and has managed to control blood sugar just by diet and exercise, his efforts are really great. For low blood sugar, he might just need some dietary modification. But if he is on medication and his blood sugar is dipping down, his prescription might need to be revised. A blood sugar of 100 is not very low (if in fasting state) and may not cause dizziness. Sometimes dehydration may cause symptoms similar to low blood sugar. So check if his water intake is adequate. Also, it is a good idea to check his blood pressure since variation in blood pressure can lead to similar symptoms. For more information consult a diabetologist online -->
