Hi doctor,

I have been experiencing dizziness, like a lightheaded feeling, and also symptoms of low blood sugar; however, when I checked my blood sugar with a monitor, it was 63 mg/dL. I drink enough water. As this is a regular occurrence, I checked my blood pressure during dizziness which was 110/68 mmHg. I told my doctor about this, and they did a blood test to check my thyroid, which came back normal. I regularly have around 2700 calories a day, but what I do is I have my evening meal around 6:30 PM and will only eat then around 10:30 AM, and I have a very active job. I paid to see a cardiologist and told him of my symptoms, and he did an ECG and echocardiogram, which were perfectly normal. Also, I experienced dizziness while wearing a Holter monitor, but my heart was normal. Usually, I get it at dinner time while standing up. It goes after eating something.

Kindly help.



Welcome to icliniq.com.

You have been thoroughly evaluated for giddiness. It would help if you met a neurologist to rule out neurological causes of dizziness. If that is fine too, it may be connected to infrequent meals and large gaps between meals. Please have frequent high-carbohydrate meals with a high glycemic index.

Please consult me for specific advice on foodstuffs.

Thank you.
