Why would i get hypoglycemia symptoms when my blood sugar is 5.4? i eat a balanced diet too this is ruining my life

No: In my 35 years of practice, I have never seen a case of reactive hypoglycemia in the absence of diabetes or GI surgery. The disorder doesn't exist, if you're overweight the symptoms are a natural response to your glucose level returning to normal. If you have diabetes, you need to reduce your medication, particularly Insulin if you're having true hypoglycemia.
