Hypothyroidism is a condition where your body doesn’t make enough thyroid hormone. 

What is the Thyroid?

The thyroid is a small butterfly-shaped organ in the front of your throat. It produces hormones that control metabolism, body temperature, energy, and overall growth.

  • How Common Is Hypothyroidism?

    About 5% of Americans age 12 and older have hypothyroidism. It’s more common in women and people over 60. 

  • Long-Term Effects

    Without treatment, hypothyroidism can lead to health problems such as heart disease, infertility, mental and cognitive issues, and other complications like joint pain, nerve damage, fatigue, and weight gain.

Causes

Autoimmune Disease

The most common cause of hypothyroidism is an autoimmune condition called Hashimoto's thyroiditis. This is where your body attacks and tries to destroy your thyroid by mistake.

Low Iodine

Iodine is a mineral your thyroid needs to make hormones. If you don’t get enough iodine in your diet, it can lead to hypothyroidism.

Certain Medications

Some medicines, like lithium, can affect your thyroid function.

Radiation Treatment

If you’ve had radiation treatment for cancer, it can affect your thyroid.

Surgery

If part or all of your thyroid is removed, it can cause hypothyroidism.

symptoms

The symptoms of hypothyroidism aren’t always clear and may feel like symptoms of other health problems. These are common symptoms to watch for.

Fatigue

You might feel tired all the time, even after a good night’s sleep.

Weight Gain

Hypothyroidism often causes weight gain, even if you’re eating the same amount of food and exercising the same as you always have. This is caused by slowed metabolism.

Sensitivity to Cold

You might always feel cold, even in warm weather, due to reduced ability to regulate body temperature.

Dry Skin & Hair

Your skin might feels rough and dry, and your hair may feel brittle or fall out easily. 

Constipation

Hypothyroidism can sometimes cause difficulty have bowel movements due to slowed bodily functioning.

Slow Heart Rate

A slower-than-usual heart rate is common, which can make you feel weak or dizzy.

Memory Problems

Lack of thyroid hormone can disrupt brain function, causing forgetfulness or trouble concentrating.

Joint Pain

Thyroid hormone is essential for bone and cartilage maintenance, and low levels can cause pain and stiffness.

Fertility Problems & Menstrual Irregularities

Hypothyroidism can impact the hormones that regulate ovulation and the menstrual cycle.

DiagnosIs

A simple blood test can check your levels of TSH (thyroid-stimulating hormone). A normal TSH level is between 0.4 and 4.0 mU/L. If your TSH is higher than that, your provider may also measure your T4 (thyroxine) levels. If your TSH is high and your T4 is low, you likely have hypothyroidism. 

Treatment

Hypothyroidism is treated with thyroid replacement therapy. The most common medication is levothyroxine, which is thyroid hormone T4. These healthy habits also help you feel your best.

Lifestyle

Eating well-balanced meals can help manage symptoms. Foods rich in selenium (found in nuts, seeds, and fish) and zinc (meat, shellfish, and beans) can support your thyroid. And, exercise can boost your energy and improve your mood.

Get Enough Sleep

Since hypothyroidism can cause fatigue, sleep is very important. Try to get seven to nine hours of sleep each night. 

Manage Stress

Stress can affect your thyroid. Find ways to manage stress, such as meditation and deep breathing.


How We Can Help

If you think you have hypothyroidism, talk to your primary care provider, who will order bloodwork to confirm the diagnosis and start you on thyroid hormone replacement therapy. If your thyroid issues are a bit tougher to treat, your provider may refer you to an endocrinologist. In this case your provider and the specialist will work together to make sure you have the care you need.
