Headaches are almost considered a usual problem, especially when there is no obvious considerable reason. While stress, due to not drinking enough water, and lack of sleep are typical causes of headaches, some others suspect thyroid issues, such as hyperthyroidism or hypothyroidism, may be a factor. If you have hyperthyroidism and you know that you have headaches, you might be able to identify the cause.
Understanding Hyperthyroidism
Hyperthyroidism happens when the thyroid gland produces more thyroid hormone than your body needs. Thyroid hormones help control many of your body’s big functions, including your speed of metabolism, your heart rate, body temperature, and your energy levels. If hormone levels rise, your body systems become overstimulated, producing symptoms such as:
- Rapid heartbeat
- Anxiety and nervousness
- Weight loss despite increased appetite
- Excessive sweating
- Tremors
- Difficulty sleeping
- Fatigue and muscle weakness
Graves’ disease is a disease that causes hyperthyroidism, the most common type of overactive thyroid disease caused by the autoimmune system.
Does Hyperthyroidism Cause Headaches?
Yes, you can get headaches if you have hyperthyroidism. It’s not one of the most common symptoms, but it can happen. Studies indicate that thyroid hormone imbalances affect blood circulation, nerve function, and inflammation, which in turn can increase the risk of headaches.
In some cases, patients with hyperthyroidism say that the hormones:
- Persistent tension-type headaches
- Migraine-like headaches
- Headaches accompanied by dizziness
- Headaches that worsen with anxiety or sleep disturbances
Overabundant thyroid hormone can cause overstimulation of the nervous system, thus leading to increased sensitivity to pain and stress. Because hyperthyroidism often produces insomnia and nervousness, these symptoms may also inadvertently cause headaches.
What Do Hyperthyroidism-Related Headaches Feel Like?
The experience changes from person to person. Some people describe it as a dull, throbbing ache across both sides of the head like a tension headache. Some people describe migraine-like symptoms that may include:
- Throbbing pain on one side of the head
- Sensitivity to light and sound
- Nausea
- Visual disturbances
Why Does Hyperthyroidism Trigger Headaches?
Several factors may explain the connection:
1. Overstimulation of the Nervous System
Elevations in thyroid hormone levels may stimulate the nervous system, leading to increased sensitivity of the brain to pain signals and headaches.
2. Sleep Disturbances
A large proportion of people with hyperthyroidism experience insomnia or poor sleep. Sleep deprivation is a frequently cited headache trigger and can exacerbate people with established migraine.
3. Increased Stress and Anxiety
Symptoms of anxiety, agitation, and anger are highly common features of people with hyperthyroidism. Persistent stress can lead to muscle tension and headache.
4. Changes in Blood Flow
Imbalances in thyroid hormone levels may interfere with the regulation of blood vessels and circulation, which could cause headaches in some patients.
When Should You See an Endocrinologist?
If you have frequent headaches along with other symptoms like a rapid heartbeat, weight loss without trying, trembling, excessive sweating, and problems with your sleep, it would be a good idea to get your thyroid checked.
An endocrinologist will run tests on your blood to determine:
- Thyroid-Stimulating Hormone (TSH)
- Free T4
- Free T3
- Thyroid antibodies, if necessary
A thyroid disorder is being able to identify and treat hyperthyroidism is often associated with a decrease in symptoms, including headaches.
If you have symptoms of hyperthyroidism, headaches, or other hormone-related concerns, the endocrinology experts at Magnet Health Endocrinologists evaluate and treat thyroid disorders, diabetes, hormonal imbalances, and metabolic disorders. With the help of a skilled team, they collaborate with patients to identify their main issue and then design a customized plan that can help them live healthy, symptom-free for a long time.
How Are Hyperthyroidism-Related Headaches Treated?
The best way to treat anxiety is to treat the underlying thyroid condition. Depending on the cause and severity of the hyperthyroidism, treatment may include:
- Anti-thyroid medications
- Beta-blockers to manage symptoms
- Radioactive iodine therapy
- Thyroid surgery in selected cases
Conclusion
Hyperthyroidism may lead to headaches, although this is not a major symptom. Overproduced thyroid hormones could overstimulate people’s nervous system or even alter blood flow. Do you have a headache with other signs of an overactive thyroid? It may be time to see an endocrinologist to determine whether your thyroid may be to blame.
