What are the symptoms of hyperthyroidism?

Hyperthyroidism is a condition that occurs when the body produces more thyroid hormones than needed. Although it is rare, it is essential to recognize its symptoms. So, what are the symptoms of hyperthyroidism, and how is it diagnosed? Continue reading to find out.

What are the symptoms of hyperthyroidism?

Hyperthyroidism affects the entire body and can cause a wide range of symptoms that may appear suddenly or develop gradually. These symptoms can be mild for some people, but severe and significantly impact the lives of others. Here are the main signs and symptoms of hyperthyroidism:

• Tachycardia (rapid heartbeat).
• Arrhythmia (irregular heartbeat).
• Heart palpitations.
• Enlarged thyroid gland, sometimes called a goiter.
• Muscle weakness.
• Bulging eyes.
• Tremors, usually mild in the hands and fingers.
• Nervousness, anxiety, and irritability.
• Increased appetite.
• Unintended weight loss.
• Eye problems, such as redness, dryness, and vision changes.
• Changes in the skin, making it thin, warm, and moist.
• Hair loss and changes, such as becoming more brittle.
• Changes in menstrual cycles.
• Heat intolerance and excessive sweating.
• Sleep problems.
• Diarrhea and frequent bowel movements.
• Fatigue.

Do All People Have the Same Symptoms?

Not everyone experiences the same symptoms. Some may have all the symptoms mentioned, while others may only have a few.

The symptoms also vary between older adults and younger adults. People over 60 years old may have symptoms similar to depression or dementia, which can be confusing. Common symptoms of hyperthyroidism in older adults include:

• Loss of appetite and weight loss.
• Irregular heartbeat.
• Feeling weak and tired during regular activities.
• Depression and avoiding social interactions.

How is Hyperthyroidism Diagnosed?

To diagnose this condition, the doctor will first take the patient’s medical history and conduct a physical examination to check for symptoms of hyperthyroidism, such as hand and finger tremors, overactive reflexes, rapid heartbeat, vision changes, and thinning skin.

Then, the doctor will request a blood test to monitor thyroid levels, including thyroxine, triiodothyronine, and thyroid-stimulating hormone. This test confirms hyperthyroidism, especially in older adults who may not have typical symptoms.

Blazma measures thyroid hormone levels in their thyroid test package and helps the doctor diagnose hyperthyroidism.

Finally, after diagnosing hyperthyroidism, the doctor may request one of the following imaging tests to determine the underlying cause:

1. Ultrasound imaging: Uses high-frequency sound waves to capture images of the thyroid gland.
2. Radioactive iodine uptake test: The patient drinks a dose of radioactive iodine, and then the neck is scanned with a device to measure the amount of iodine absorbed by the thyroid.
3. Thyroid scan: After drinking a dose of radioactive iodine, the patient’s iodine uptake by the thyroid is measured. The patient lies on a table, and several images of the neck are taken with a gamma camera to identify specific thyroid issues.
