Hypothyroidism, or an underactive thyroid, happens when the thyroid gland fails to produce enough thyroid hormones. This gland, located in the front of the neck, controls essential bodily functions like metabolism, energy levels, and temperature. When the thyroid doesn’t produce enough hormones, the body’s processes slow down, which can lead to several noticeable symptoms and health issues. Knowing the symptoms, causes, and when to seek help is key to managing hypothyroidism.
What Causes Hypothyroidism?
Several factors can lead to hypothyroidism, including:
- Hashimoto’s Thyroiditis: This autoimmune condition is one of the most common causes of hypothyroidism. The immune system mistakenly attacks the thyroid gland, reducing its ability to produce hormones.
- Thyroid Surgery: If part or all of the thyroid gland is surgically removed, the gland’s hormone production decreases or stops, often leading to hypothyroidism.
- Radiation Therapy: Treatment for cancers in the neck or head, such as thyroid or throat cancer, can damage the thyroid gland and reduce hormone production.
- Medications: Certain medications, like lithium (used to treat bipolar disorder), can interfere with thyroid function, sometimes leading to hypothyroidism.
- Iodine Deficiency or Excess: Iodine is essential for thyroid hormone production. Too little or too much iodine can affect thyroid function, although iodine-related hypothyroidism is rare in regions with sufficient dietary iodine.
- Pituitary Gland Issues: Sometimes, hypothyroidism stems from a pituitary gland problem, which affects its ability to signal the thyroid to produce hormones.
Recognizing the Symptoms of Hypothyroidism
Hypothyroidism symptoms can vary, with many symptoms often overlooked or mistaken for signs of aging. Here are some common signs to watch for:
- Fatigue and Weakness: A common sign of hypothyroidism is feeling constantly tired, even after a full night’s sleep. This fatigue can also cause muscle weakness, especially in the arms and legs.
- Weight Gain: Unexplained weight gain, even with regular diet and exercise, can indicate hypothyroidism. This happens because the reduced hormone levels slow down the body’s metabolism, causing weight gain even if calorie intake doesn’t change.
- Cold Sensitivity: People with hypothyroidism often feel colder than those around them, even in warm weather, due to a slower metabolic rate affecting body temperature regulation.
- Dry Skin and Hair: Hypothyroidism can make the skin dry, rough, and pale. Hair can also become dry, brittle, and more prone to thinning or hair loss.
- Slow Heart Rate: In some cases, hypothyroidism can lead to a slower-than-normal heart rate (bradycardia). This occurs because low thyroid hormones affect heart function.
- Depression and Mood Changes: A drop in thyroid hormone levels can lead to mood changes, including depression, irritability, and difficulty concentrating.
- Constipation: Slower digestion is another symptom, and many people with hypothyroidism experience constipation as a result.
- Muscle Aches and Joint Pain: Low thyroid hormone levels can cause muscle stiffness, aches, and joint pain, particularly in the shoulders and hips.
- Menstrual Irregularities: In women, hypothyroidism can cause heavier and more prolonged menstrual periods due to hormonal imbalances. Fertility issues can also occur in severe cases.
- Memory Issues: Some individuals with hypothyroidism experience “brain fog,” memory lapses, or general mental sluggishness.
When to Seek Help for Hypothyroidism Symptoms
Hypothyroidism can cause more serious health complications if left untreated, such as heart disease, high cholesterol, and an increased risk of certain types of anemia. If you notice any of these symptoms, it’s essential to seek medical advice.
