Hypothyroidism

Hypothyroidism can be easy to overlook at first. You may feel more tired than usual, notice subtle weight changes, or just feel off without a clear reason. Because symptoms often develop slowly, they’re easy to attribute to stress, aging, or a busy schedule.

Hypothyroidism happens when your thyroid gland doesn’t produce enough thyroid hormones, which can cause many of your body’s systems to slow down. If you’re experiencing symptoms of hypothyroidism in San Antonio, understanding what’s behind these changes is the first step toward getting clear answers and the right care.

Common Symptoms of Hypothyroidism

Hypothyroidism often develops gradually. Early symptoms can be easy to miss or attributed to stress or aging. As thyroid-related hormone levels drop, symptoms become more noticeable and may include:

Ongoing fatigue
Low energy
Increased sensitivity to cold
Constipation
Dry skin
Weight gain without a clear reason
Puffiness in the face
Hoarseness
Thinning hair
Muscle weakness or aches
Slower heart rate
Low mood
Difficulty concentrating
Memory changes

For women, menstrual cycles may also become heavier or irregular.

What Causes Hypothyroidism?

The most common cause is an autoimmune condition called Hashimoto’s disease. Your immune system attacks the thyroid, which can lower hormone levels.

Other causes include:

Thyroid surgery that removes part or all of the gland
Radiation treatment to the head or neck
Inflammation of the thyroid, called thyroiditis
Certain medications, such as lithium or amiodarone
Problems with the pituitary gland
Hormonal changes during or after pregnancy
Iodine imbalance

How Is Hypothyroidism Diagnosed?

Because symptoms can overlap with many other conditions, if hypothyroidism is suspected, a blood test is used to confirm it. Your doctor will check:

Thyroid-stimulating hormone (TSH), which is the most sensitive indicator
Free T4 to see how well the thyroid is functioning

Sometimes, testing for thyroid antibodies is done to confirm an autoimmune cause.

How Hypothyroidism Is Treated

Most people take a daily medication called levothyroxine. It replaces the hormone that your thyroid is not making. Once the correct dose is established, a noticeable improvement in energy and general wellness can be seen.

There are a few important details to keep in mind when starting levothyroxine:

It is taken once daily, usually on an empty stomach
It may take several weeks to feel the full effect
Dosing is adjusted based on follow-up blood tests
Certain supplements and foods, especially calcium and iron, can interfere with absorption

What Happens If Hypothyroidism Is Not Treated?

Untreated hypothyroidism can affect multiple systems in the body, leading to:

High cholesterol levels
Increased risk of heart disease
Nerve problems, such as numbness or tingling
Infertility
Menstrual changes
Slowed mental function

In rare instances, severe hypothyroidism can lead to a condition called myxedema coma. Despite the name, it does not always involve a true coma, but it does cause life-threatening slowing of body functions, with symptoms such as:

Confusion
Drowsiness
Low body temperature
Slowed heart rate
Breathing difficulties

Myxedema coma is a medical emergency and requires immediate treatment.

If you’re noticing signs of hypothyroidism, it’s worth looking into. Pay attention to patterns such as:

Ongoing fatigue that does not improve with rest
Unexplained weight gain
Hair thinning or dry skin
Changes in menstrual cycles

Thyroid conditions can run in families, too. If you have a family history or symptoms, a simple blood test can help clarify what is going on.
