What Is Hunger Headache?

Overview

Have you ever experienced a dull headache while you were hungry that vanished after eating? Are you interested in learning some practical tips to prevent such headaches?

A hunger headache is a mild ache that arises when you haven't eaten for an extended period of time. Although it typically subsides after having a meal, there are methods to avoid or relieve such headaches, even if you aren’t able to consume regular meals. When your blood sugar levels drop below normal levels, which is known as low blood sugar or hypoglycemia, you may experience a "hypo." This can occur for various reasons, such as taking excessive diabetes medication, not eating enough, or engaging in excessive physical activity without eating. When your blood sugar drops too low, you may encounter symptoms like sweating, shaking, confusion, and, in severe cases, fainting. It's crucial to receive treatment for low blood sugar promptly to prevent further complications. This article will provide you with information on hunger headaches, their symptoms, management, and treatment, as well as their diagnosis.

Causes of hunger headache

There are two types of headaches: primary and secondary. Primary headaches, like migraines and tension headaches, have no known cause or underlying health problem. Secondary headaches, on the other hand, are caused by an underlying medical condition, like a brain tumor, an aneurysm, or exposure to certain substances. The most common type of secondary headache is caused by a problem with the body's internal system that maintains balance and stability, called homeostasis. If you get a headache from fasting, that could be a sign of a problem with homeostasis.

Both hunger and low blood sugar headaches can occur due to various reasons. Not drinking enough fluids, following new diets, consuming too much or too little coffee or soda, eating at irregular times, having a busy day without eating, not getting enough sleep, and skipping meals are a few examples. If you have diabetes, you're at risk of low blood sugar due to factors like taking too much insulin or other diabetes medications, skipping meals, not consuming enough carbohydrates, engaging in intense exercise, or drinking alcohol. Although it's rare, low blood sugar can also affect individuals without diabetes, and at times, it may happen without any apparent reason.

Signs and symptoms of hunger headache

It's important to be aware that low blood sugar affects everyone differently, and it's crucial to recognize the symptoms that you personally experience. Some common early signs of low blood sugar include sweating, fatigue, dizziness, hunger, and shaking. You may also feel anxious, moody, or experience palpitations. If left untreated, low blood sugar can cause weakness, blurred vision, confusion, slurred speech, or even seizures. It's also possible to experience low blood sugar while sleeping, which can cause you to wake up during the night or feel tired and have damp sheets from sweating in the morning. To prevent complications, it's vital to monitor your blood sugar levels regularly and seek medical attention if you experience any of these symptoms. Many people report that skipping meals or fasting can trigger migraine or tension-type headaches. Studies show that between 39% to 82% of adults who experience these types of headaches believe that not eating is the cause. In a recent study with over 1,200 migraine patients, 57% reported that not eating was a trigger for their headaches, ranking it alongside stress, hormonal changes, and sleep disturbances as the most common triggers. Fasting as part of religious practices like Yom Kippur and Ramadan has also been linked to an increased risk of headaches, with longer periods of fasting associated with a higher risk. Remember, recognizing the signs early and seeking prompt medical attention can make all the difference in managing low blood sugar.¹

Management and treatment for hunger headache

If you get headaches because of low blood sugar levels, you can manage them by eating small, healthy meals often throughout the day. Don't skip meals, especially breakfast. Instead of a sandwich, have a proper meal for lunch, and if you have lunch early, have a snack in the afternoon to avoid getting too hungry. If you wake up with a headache, try having a healthy snack before bed. To keep your blood sugar levels steady, focus on eating a healthy diet with lots of fruits and vegetables, and limit your intake of cakes, biscuits, ice cream, processed foods, and ready meals. If you're trying to lose weight, aim for a gradual, long-term approach to make it easier to keep the weight off.

Diagnosis

To diagnose a hunger headache, you can rely on your body's signals. If you experience a dull pain in your head and it has been a while since you last ate, it is likely that you are experiencing a hunger headache. These headaches are often associated with low blood sugar levels, which can occur when you go for extended periods without eating. If eating something makes the headache go away, it is a good indication that it was caused by hunger. However, if your headaches persist or are severe, it is advisable to consult a doctor to rule out any underlying medical conditions.
