People suffering from diabetes are highly susceptible to headaches. In fact, persistent headache is an obvious sign of diabetes. Diabetes headaches can be due to various reasons.
Hyperglycemia is a term that refers to having too much glucose circulating in the blood as a result of lack of insulin production in the pancreas, or cellular resistance to insulin. Hyperglycemia is a serious condition since high concentrations of glucose can be toxic to the blood vessels and the nerves.
According to health experts, headache is considered an early symptom of hyperglycemia and is usually accompanied with fatigue, confusion and blurred vision. In the absence of insulin therapy, hyperglycemia can lead to the buildup of ketones which are waste products in both the urine and blood. Buildup of ketones that can lead to coma and death.
Hypoglycemia happens when there is too little amount of glucose in the blood for the body to use for energy. If you have diabetes, hypoglycemia can occur if you mismanaged your insulin therapy. If you do not have diabetes, not eating enough nutrients like carbohydrates, which the body needs to breakdown to glucose, may result in hypoglycemia. Hypoglycemia is a serious condition because glucose is the main source of energy for the brain. Without enough glucose our brains are not able to function properly.
According to the American Heart Association, dull headache is an early sign of hypoglycemia and can come with other related symptoms like cloudy vision, dizziness, sweating, confusion and tremors. If you do not eat sufficient carbohydrates, like fruits, pasta, breads or juices, hypoglycemia can lead to loss of consciousness, convulsions and even death.
If you’re suffering from diabetes, then you should know that you’re at high risk of glaucoma. Glaucoma is an eye disease where the optic nerve is damaged and can lead to a progressive and irreversible blindness. Diabetes is often accompanied by higher incidences of glaucoma because the optic nerve is usually sensitive to a high blood glucose.
Glaucoma can result in increased pressure in the eye, and can lead to eye pain as well as headaches. Headaches related to glaucoma is like a sharp and stabbing pain right above and behind the eye. It can come with blurred and sudden loss of vision, and sometimes accompanied with vomiting and nausea.
Diabetes will can also lead to neuropathy, a nerve injury that is a result of high blood sugar. Our brain consists of several neurons and this includes the larger cranial nerves. Neuropathy on the cranial nerves can lead to severe and pounding headaches.
