well this certainly deserves to be investigated by a medical professional. i can think of a number of conditions that could cause the symptoms you describe. hypoglycemia possibly. but also seizure and stroke. so it's important to get a true diagnosis and not rely on what he was told decades ago as a child. i'd suggest you start by calling your primary health care provider for an exam and blood work. that will give you and your husband a good start. wishing you all the best!
he gets a headache light headed dizzy slurred speech and sometimes a limp when he walks can tell coming most times. this is on my husband when he was little he was told it was hypoglicemia but neither of us think that is correct. im curious to know what it is and if it can become serious or not
