What Is Hashimoto’s Thyroiditis?
Hashimoto’s thyroiditis is a condition where your immune system attacks your thyroid gland by mistake. The thyroid is a small gland in your neck that helps control your body’s energy. When it gets damaged, your body slows down.
What Causes It?
Hashimoto’s is an autoimmune disease, which means your body attacks itself. The exact cause is unknown, but it tends to run in families and is more common in women.
Symptoms
You might not have symptoms at first. But over time, you may notice:
Feeling very tired
Gaining weight
Dry skin
Feeling cold, even when it’s warm
Trouble going to the bathroom (constipation)
Sad or depressed feelings
Hair thinning or hair loss
Puffy face
Slow heartbeat
Trouble thinking clearly
Irregular or heavy periods (for women)
Treatment
Doctors treat Hashimoto’s with thyroid hormone pills. These pills replace the hormone your body no longer makes. You will probably need to take them every day for life. Your doctor will check your blood to make sure your dose is right.
Diet and Special Precautions
There is no special diet that cures Hashimoto’s, but you may feel better if you:
Eat healthy foods like fruits, vegetables, and whole grains
Get enough selenium (found in foods like Brazil nuts and tuna)
Avoid too much iodine or soy (check with your doctor)
Precautions:
Take your medicine on an empty stomach at the same time each day
Do not stop your medicine unless your doctor tells you
Get blood tests regularly to check your hormone levels
Tell your doctor if you feel worse or different
When to Call the Home Health Nurse or Doctor
Call if you:
Feel more tired than normal
Have trouble thinking clearly
Gain or lose weight suddenly
Feel cold all the time
Have constipation
Notice hair loss or dry skin
Feel sad or depressed
When to Go to the Emergency Room
Go to the ER if you:
Feel confused or pass out
Have chest pain or trouble breathing
Have a very slow heartbeat
Feel extremely cold and can’t warm up
Cannot wake up or stay awake
These could be signs of a serious and rare problem called myxedema coma.
