Hey there, your symptoms are suggestive of hypoglycemic episodes, especially since they occur when there is a delay in meals and improve after eating. But with normal
fasting blood sugar and
HbA1c, this needs further evaluation. possibility can include
thyroid dysfunction, anemia, anxiety-related symptoms.
Or could be your recent gastritis may also be contributing if your food intake has reduced.
Next Steps
I would advise
TSH with Free T4, CBC (if not done recently), serum
electrolytes, and blood glucose during an episode of symptoms (or as advised by your treating physician). Also a review of your current medications plus most importantly dietary pattern changes.
Health Tips
Avoid prolonged fasting. Have small, frequent meals with adequate protein and complex carbohydrates. Stay well hydrated. If you experience severe palpitations, loss of consciousness, chest pain, or persistent symptoms despite eating, seek immediate medical attention.
