Patient's Query

Hello doctor,

I have been experiencing dizziness and lightheadedness feeling and also symptoms of low blood sugar. However, when I checked my blood sugar with a monitor, it was 113.51 mg/dL. As this was regular, I checked my blood pressure during dizziness which was 110/68 mm of Hg. I told my doctor about this, and they did a blood test to check my thyroid, which was normal. I eat 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 consulted a cardiologist and told him of the symptoms, and he did an ECG and echocardiogram, which were perfectly normal. Kindly help.


Welcome to icliniq.com.

Your symptoms could be related to epilepsy seizures. The EEG (electroencephalogram) shows many muscle and ocular artifacts. There is also focal slowing in the fronto- central leads, which could be related to these attacks of falling. I would also recommend performing an ambulatory 24 to 48 hours ECG (electrocardiogram) to investigate for possible cardiac arrhythmia.

I hope this helps.

Thank you.
