What is Autoimmune Thyroiditis?
Your thyroid is a small gland in front of your neck that makes hormones that help control just about every organ. When your thyroid doesn’t make enough of these hormones, your body can’t work right. That can affect your energy level, mood, and weight.
If your thyroid becomes inflamed, you have thyroiditis. Sometimes it happens because your body makes antibodies that attack your thyroid by mistake. This condition is called autoimmune thyroiditis, chronic lymphocytic thyroiditis, Hashimoto’s thyroiditis, or Hashimoto’s disease.
Causes
Doctors don’t fully understand why your immune system misfires this way. It could be set off by a faulty gene, a virus, or something else. Or it could be a combination of causes.
Could You Get It?
You may be more likely to get autoimmune thyroiditis if you:
- Are a woman
- Are middle-aged
- Have another autoimmune disorder like lupus, type 1 diabetes, or rheumatoid arthritis
- Are related to someone who has autoimmune thyroiditis
- Have been exposed to environmental radiation
Symptoms
You may not have any in the beginning.
As the disease goes on, your thyroid may become enlarged, a condition called a goiter. The front of your neck will look swollen, and it might make your throat feel full. It may not hurt. Left alone, the thyroid will eventually shrink on its own, but that doesn’t mean you’re cured. That just means your thyroid is damaged.
A damaged thyroid can’t do its job, which leads to hypothyroidism -- too little of the thyroid hormones. Symptoms can include:
- Tiredness
- Sensitivity to cold
- Puffy face
- Trouble pooping
- Enlarged tongue
- Pale, dry skin and brittle nails
- Hair loss
- Weight gain
- Muscle aches and joint pain
- Depression
- Memory lapse
- Heavy menstrual bleeding
Diagnosis
Your doctor will order blood tests to check your thyroid hormone levels. The tests also look for something called thyroperoxidase antibodies.
You also might have an ultrasound so your doctor can look at your thyroid, especially if your blood test results aren’t clear. Your doctor might spot the problem through regular blood tests even if you don’t have any symptoms, especially if they’re aware that your family has a history of thyroid problems.
Treatment
The usual therapy is a prescription medicine called levothyroxine (Levo-T, Levothroid, Levoxyl, Synthroid, Tirosint, Unithroid). It’s a man-made version of what a healthy thyroid makes.
Your doctor will keep an eye on you and may have to adjust your dosage every once in a while. You’ll need to take medicine for the rest of your life.
Some foods, like a high-fiber diet or soy products, can mess with levothyroxine. You should also let your doctor know if you take:
- Iron supplements
- A cholesterol medicine called cholestyramine (Locholest, Prevalite, Questran)
- Antacids that have aluminium hydroxide
- An ulcer medicine called sucralfate (Carafate)
- Calcium supplements
