Thyroid inflammation, also known as thyroiditis, can be confusing for many people. The thyroid is a small, butterfly-shaped gland in your neck. Even though it’s small, it plays a big role in controlling your body’s energy, metabolism, and overall health.
When the thyroid becomes inflamed, it can lead to different problems. Some people may feel just a little discomfort, while others may experience changes in hormone levels that affect their whole body. Let’s take a closer look at what causes this condition, explained in simple terms.
One of the most common causes is an autoimmune disease called Hashimoto’s thyroiditis. This happens when your immune system, which is supposed to protect you, mistakenly attacks the thyroid. This ongoing attack leads to inflammation and can cause the thyroid to stop working properly.
Researchers say that family history plays a big part—if your parents or siblings have thyroid problems, you might have a higher risk too. Certain genes seem to make the immune system more likely to make this mistake.
Another cause is viral infections. When you catch something like the flu or a cold, your immune system fights back. But sometimes, it also causes swelling in the thyroid by mistake.
This type of thyroiditis is called subacute thyroiditis. It can cause pain in the neck, fever, and a feeling of being sick. The good news is that most people recover fully after a few weeks or months.
Some women get thyroid inflammation after giving birth. This is called postpartum thyroiditis. During pregnancy, the immune system is lowered to protect the baby. But after birth, the immune system can suddenly become too active and start attacking the thyroid.
At first, the thyroid may make too much hormone, but later it might slow down. This can cause tiredness, weight changes, and mood swings. Women who’ve had thyroid problems or other immune diseases are more likely to get this.
Certain medications can also cause thyroid inflammation. For example, a drug called amiodarone, used for heart problems, and another called interferon, used for hepatitis C and some cancers, can both affect the thyroid. Doctors often check thyroid levels before and during treatment with these medications to avoid problems.
Radiation can also harm the thyroid. People who have had radiation treatments for cancer in the head or neck area, or who have been exposed to radiation in the environment, may develop thyroiditis.
Radiation can damage the thyroid and lead to changes in how it works. Higher amounts of radiation increase this risk, and doctors usually keep a close eye on patients who’ve been exposed.
Iodine is another important piece of the puzzle. Your thyroid needs iodine to make hormones. But having too little or too much can cause trouble. Not enough iodine can lead to goiter (a swollen thyroid) and low hormone levels.
Too much iodine can also inflame the thyroid and cause it to make too much hormone. Getting the right amount of iodine from food or supplements is important.
By learning about these causes, people can spot problems early and get help. Even though thyroid inflammation can be uncomfortable, it is often treatable. Regular check-ups and knowing your family history can make a big difference. When we understand more about our thyroid, we can take better care of our health and feel more in control.
