Graves' disease
Graves' disease is an immune system disorder that results in the overproduction of thyroid hormones, known as hyperthyroidism. It is the most common cause of hyperthyroidism and can affect the eyes, skin, and metabolism.
Overview
Graves' disease is an immune system disorder that results in the overproduction of thyroid hormones, known as hyperthyroidism. It is the most common cause of hyperthyroidism and can affect the eyes, skin, and metabolism.
Understand this condition
The immune system mistakenly attacks the thyroid gland, causing it to produce too much hormone. This flood of hormones speeds up the body's internal clock, affecting heart rate and energy consumption. Eventually, this overactivity strains multiple organs and disrupts the body's normal chemical balance.
Why it happens
The body's immune system creates an antibody that mimics the signal to produce thyroid hormone. This constant, false signal causes the thyroid to bypass its normal regulatory checks. Over time, the resulting high metabolism can lead to heart complications and physical exhaustion.
