Causes & symptoms of underactive & hypothyroidism in female
Hypothyroidism, also known as an underactive thyroid, is a common condition in females that occurs when the thyroid gland doesn’t produce enough hormones. This slows down the body’s metabolism and affects overall health. Here's a quick breakdown:
Common Causes in Females:
• Hashimoto’s Thyroiditis – An autoimmune disorder where the immune system attacks the thyroid.
• Iodine Deficiency – Low iodine intake can reduce thyroid hormone production.
• Thyroid Surgery or Radiation – Removing or damaging the thyroid affects its function.
• Medications – Certain drugs can interfere with thyroid hormone levels.
• Hormonal Changes – Pregnancy or menopause can trigger thyroid imbalance.
Major Symptoms in Women:
• Fatigue – Constant tiredness, even with rest.
• Weight Gain – Unexplained increase in body weight.
• Dry Skin & Hair – Brittle hair and flaky skin are common.
• Cold Intolerance – Feeling cold even in warm temperatures.
• Menstrual Irregularities – Heavy, missed, or prolonged periods.
• Depression & Mood Swings – Emotional imbalance and brain fog.
• Constipation – Slowed digestion due to hormonal slowdown.
Early diagnosis and treatment can help manage symptoms effectively. If you notice these signs, consult a doctor and get your thyroid tested.
The thyroid is a small, butterfly-shaped gland located in the front of the neck. It might be small in size, but it plays a powerful role in regulating your metabolism, energy levels, heart rate, and even mood. When the thyroid doesn’t produce enough hormones—a condition known as hypothyroidism or underactive thyroid—the entire body slows down.
Women are more prone to hypothyroidism than men, especially after the age of 30, during pregnancy, or after menopause. The symptoms can often be subtle at first, but if left untreated, this condition can severely affect your health and well-being.
[Let’s explore the common causes and symptoms of hypothyroidism in females, so you know what to look out for and when to seek help.]
🔍 What is Hypothyroidism?
Hypothyroidism occurs when the thyroid gland fails to produce sufficient amounts of thyroxine (T4) and triiodothyronine (T3) hormones. These hormones are essential for regulating how the body uses energy.
When levels are too low, it leads to a slowdown of body functions—including metabolism, digestion, brain activity, and body temperature regulation.

⚠️ Causes of Underactive Thyroid in Females
Hypothyroidism in women can be caused by various factors, ranging from autoimmune diseases to pregnancy-related hormonal shifts. Below are the most common causes:
1. Hashimoto’s Thyroiditis
• The most common cause of hypothyroidism in women.
• It’s an autoimmune condition where the body’s immune system mistakenly attacks thyroid tissue.
• Over time, this attack damages the thyroid gland, reducing hormone production.
2. Iodine Deficiency
• Iodine is essential for producing thyroid hormones.
• A lack of iodine in the diet can lead to goiter and underactive thyroid.
• Though rare in developed areas due to iodized salt, it's still a concern in some populations.
3. Thyroid Surgery
• Women who’ve had partial or complete thyroid removal due to nodules, cancer, or goiter may develop hypothyroidism post-surgery.
4. Radiation Therapy
• Radiation treatment for neck or head cancers can damage the thyroid gland.
• It reduces or stops hormone production, leading to an underactive thyroid.
5. Certain Medications
• Drugs such as lithium, interferon, amiodarone, or methimazole may interfere with thyroid function.
• These medications are often prescribed for mood disorders or heart conditions.
6. Pregnancy-Related Hypothyroidism
• Some women develop thyroid problems during or after pregnancy, called postpartum thyroiditis.
• It can temporarily or permanently affect thyroid hormone levels.
7. Pituitary Gland Dysfunction
• The pituitary gland controls thyroid hormone production through TSH (thyroid-stimulating hormone).
• Any damage or tumor in this gland can impact thyroid function.
8. Genetic Factors
• Family history of thyroid disease increases your risk.
• Women with mothers or sisters who have thyroid issues should be particularly watchful.
9. Aging
• As women age, especially post-menopause, the risk of developing an underactive thyroid increases.
• Regular thyroid function tests are often recommended for women over 50.
🚨 Symptoms of Hypothyroidism in Females
Symptoms of hypothyroidism in women can vary greatly depending on the severity and duration of hormone deficiency. Many are subtle and mistaken for stress, aging, or lifestyle changes. Here’s a detailed look at the most common symptoms:
1. Chronic Fatigue and Weakness
• Feeling tired even after sleeping well.
• Low energy levels throughout the day.
• Muscles may feel weak or ache easily.
2. Weight Gain Without Changes in Diet
• Slow metabolism leads to unexplained weight gain.
• Even with diet control and exercise, losing weight becomes hard.
3. Dry and Itchy Skin
• Skin becomes rough, dull, and flaky.
• You may also experience brittle nails and cracked heels.
4. Hair Thinning and Hair Loss
• Hair becomes dry, coarse, and prone to falling out.
• Eyebrows may thin, especially on the outer edge.
5. Cold Sensitivity
• Always feeling cold, even in warm environments.
• Slowed metabolism reduces body heat production.
6. Depression and Mood Swings
• Mood disturbances, irritability, and low motivation.
• Brain fog and difficulty concentrating (called "thyroid fog").
7. Irregular or Heavy Menstrual Periods
• Menstrual cycles may become longer, heavier, or more painful.
• Some women may also experience missed periods or infertility.
8. Constipation
• Slow digestive function is a hallmark sign of hypothyroidism.
• Constipation becomes frequent and harder to manage.
9. Memory Issues and Difficulty Focusing
• Poor concentration, forgetfulness, and mental confusion.
• Feeling mentally "sluggish" or unable to process thoughts.
10. Puffy Face and Swollen Eyes
• Water retention can cause puffiness, especially in the face.
• Eye swelling or "bags" under the eyes may be noticeable.
11. Slow Heart Rate
• Bradycardia (slow heartbeat) can lead to fatigue and dizziness.
• In extreme cases, it can affect heart health.
12. Hoarseness or Deep Voice
• Swelling around the thyroid can cause voice changes.
• A hoarse or raspy voice is a subtle but common symptom.
13. Infertility and Pregnancy Complications
• Hypothyroidism can disrupt ovulation.
• Increases the risk of miscarriage, preeclampsia, and low birth weight in pregnancy.
14. Carpal Tunnel Syndrome
• Numbness, tingling, or pain in the hands and fingers.
• Often occurs due to fluid retention and nerve compression.
15. Swelling in the Neck (Goiter)
• The thyroid may become enlarged, creating visible or physical swelling.
