Conditions that affect your thyroid 6
Each guide covers early signs, labs to ask about, and when to see a doctor.
Graves' disease
AutoimmuneThe most common cause of an overactive thyroid. Antibodies switch the thyroid 'on' so it makes too much hormone.
Hashimoto's thyroiditis
AutoimmuneThe most common cause of an underactive thyroid in the US. The immune system slowly damages the thyroid, so it makes less hormone over time.
Fertility challenges
ChronicInfertility means not getting pregnant after 12 months of trying, or after 6 months if you're 35 or older. Many causes are treatable, and both partners should be evaluated.
Weight management
ChronicBody weight is shaped by genes, hormones, sleep, stress, medicines, and health conditions, not willpower alone. Care here focuses on health and on finding medical causes of weight change, at any body size.
Anxiety
ChronicWorry, fear, or physical tension that's out of proportion to the situation and gets in the way of daily life. Physical causes such as thyroid or hormone changes can drive or worsen it.
Depression
ChronicA persistent low mood or loss of interest that lasts at least 2 weeks and affects how you think, feel, and function. It's a medical condition, not a weakness, and it's treatable.
