Hyperthyroidism is a condition where the butterfly-shaped gland in your neck becomes overactive and produces too much thyroxine hormone. 
Also known as overactive thyroid, it can speed up your metabolism significantly. The condition may cause unpleasant symptoms such as anxiety, weight loss, muscle weakness, heartbeat irregularities, and inflammation in the thyroid gland.
An overactive thyroid is a serious condition and needs to be treated as early as possible. Some essential oils for hyperthyroidism can help you to relieve some of the symptoms.
Remember, essential oils are a natural and complementary treatment. They are not an alternative to your conventional treatment. You must consult with a doctor before using them.
There isn’t much research on the use of essential oils for hyperthyroidism. But some study suggests that they may control hormone production.

Causes & Symptoms of Hyperthyroidism
Graves disease is the most common type of hyperthyroidism. It’s an autoimmune disease that makes your body produce an antibody named thyroid-stimulating immunoglobulin (TSI). The thyroid gland produces too much hormone due to TSI. 
Another reason behind overactive thyroid is a nodular goiter. It’s a lump in the thyroid gland that makes it produce too much thyroid hormone.
Besides, inflammation in the thyroid gland may also generate some symptoms of hyperthyroidism.
The possible symptoms of hyperthyroidism include:
- Anxiety and nervousness.
- Extreme mood swing.
- Sudden weight loss.
- Feeling very tired and weak.
- Sleeping problem.
- Fast and irregular heartbeats.
- Changes in menstrual cycles.
- Frequent bowel movement.
- Skin is thinning.

Essential oils are usually safe. But they can also create trouble if you do not know how to use them. You need to maintain some safety measures to avoid any adverse effects.
- Dilute the essential oils with a good carrier oil. Some of the essential oils are quite strong. Thus, they can irritate your skin.
- If you’re allergic to any particular essential oil, do not use it.
- Test the oil on a small part of your skin to find out if the oil suits you.
- If you’re pregnant or a breastfeeding mom, ask your doctor before using any essential oils.
When Should You See a Doctor?
