Hypothyroidism (underactive thyroid) in females commonly presents with fatigue, unexplained weight gain, cold intolerance, dry skin, brittle nails, hair thinning or loss, constipation, depression, brain fog, and menstrual irregularities—including heavier or more frequent periods, or even amenorrhea (absence of periods). These symptoms often develop gradually and can be mistaken for other conditions like stress or menopause.

Hyperthyroidism (overactive thyroid) in females typically causes unintentional weight loss, rapid or irregular heartbeat, heat intolerance, anxiety, irritability, insomnia, tremors, and lighter or less frequent menstrual periods. In some cases, it may lead to a continuous menstrual cycle or severe menstrual bleeding.

Both conditions can cause an enlarged thyroid (goiter), mood changes, fertility issues, and impact bone health—especially in postmenopausal women. Thyroid disorders are significantly more common in women, particularly during reproductive years, postpartum, and around menopause.

Key takeaway: If you experience persistent fatigue, unexplained weight changes, mood swings, or menstrual irregularities, consult a healthcare provider. A simple blood test (measuring TSH, T3, and T4) can diagnose thyroid dysfunction. Early detection and treatment—often with medication—can effectively manage symptoms and prevent complications.

All above symptoms, except the weight gain. I had brain fog, woke up in a confusing about what to do. Words would go away, could not recall everyday items and people. My boss made fu of me, knowing that I was suffering. I was terrified. My primary doctor refused to help. My psychiatrist just wanted to give ne anti depressants. I refused. Finally, my rumatoligist tested me for everything, 7 vials of blood. I am off water pills ,blood pressure medication and arthritis pills. More on reddit.com

What were your first symptoms before you were diagnosed?

Super depressing, but it happened when I became pregnant and had it terminated. I grew a goiter and gained 30lbs. My aunt has it too, had to have her thyroid surgically removed. In fact, every woman in my family has some level of hypothyroidism (specifically Hashimotos), and it always rears it's ugly head after they've had children. I've been basically normal since going back on birth control (except for the lump in my neck, still getting it checked for cancer yearly)

When it happened I gained weight, got super depressed, was always tired... but all of that was easily explained away by my having an abortion. That is, until it just didn't end. It went on for years before I was diagnosed. Somehow I've normalized again, without ever having had medication. My health insurance ran out, and by the time I was covered again my doctor said I didn't need it. Go figure.

How do thyroid hormones affect heart function?
Thyroid hormones have a strong connection to heart function. Too much thyroid hormone can increase the risk of a rapid or irregular heartbeat (tachycardia and atrial fibrillation). Too little thyroid hormone can lead to a low heart rate (bradycardia) and an enlarged heart (cardiomyopathy). These heart conditions can also be a sign that a person has an undiagnosed thyroid problem.

Consequently, patients with hypothyroidism often gain weight rapidly without altering their diet. Another common warning sign of thyroid issues is problems with vision or the eyes. This symptom can present in both hyperthyroidism and hypothyroidism patients, though it is slightly more common in patients with an underactive thyroid.
