10 Warning Signs Your Thyroid Might Not Be Working Properly

News

You should have known this sooner.

🧠 1. Fatigue and Sluggishness

  • Constant tiredness even after a full night’s sleep may indicate hypothyroidism.
  • The thyroid hormone plays a key role in energy regulation—low levels slow down the body’s metabolism.

💇‍♀️ 2. Hair Thinning or Hair Loss

  • Unexplained hair loss, especially at the scalp’s center, can be a result of imbalanced thyroid hormones.
  • Both hypo- and hyperthyroidism can disrupt hair growth cycles.

❄️ 3. Feeling Cold All the Time

  • If you’re constantly cold while others are comfortable, it could mean an underactive thyroid, which slows metabolism and body heat production.

❤️ 4. Rapid or Irregular Heartbeat

  • Hyperthyroidism can cause your heart to beat faster or irregularly, especially during rest.
  • Palpitations, skipped beats, or pounding in the chest may occur.

🧠 5. Depression or Mood Changes

  • A malfunctioning thyroid can cause low serotonin levels, leading to depression, anxiety, or mood swings.
  • Hypothyroidism is especially linked with emotional imbalance.

⚖️ 6. Unexplained Weight Gain or Loss

  • Gaining weight despite dieting could indicate hypothyroidism.
  • Losing weight rapidly without trying might suggest hyperthyroidism.

🩸 7. Menstrual Irregularities or Fertility Problems

  • Heavy, irregular, or missed periods may result from thyroid issues.
  • It can also affect ovulation, making conception difficult.

 8. Digestive Issues

  • Hypothyroidism may cause constipation due to a slower digestive process.
  • Hyperthyroidism may lead to frequent bowel movements or diarrhea.

🧴 9. Dry Skin and Brittle Nails

  • Dry, flaky skin and splitting nails are common in people with hypothyroidism.
  • The condition affects skin hydration and collagen production.

10. Body Odor (Especially Underarm Odor)

  • Unusual or strong underarm body odor can be linked to thyroid imbalance, especially hyperthyroidism.

  • It causes overactive sweat glands and changes in body chemistry, which can intensify odor.

  • Additionally, thyroid issues can disrupt liver function, impacting toxin breakdown and contributing to body odor.

⚠️ Why Women Are More Susceptible:

  • Women are 5 to 8 times more likely to develop thyroid disorders than men.
  • Hormonal events such as pregnancy, postpartum changes, and menopause increase the risk.
  • Autoimmune conditions like Hashimoto’s thyroiditis are more common in women.

What To Do:

  • If you notice several of these symptoms, consult a healthcare provider.
  • A simple blood test (TSH, T3, T4) can evaluate thyroid function.
  • Lifestyle changes, medication, and nutritional support (iodine, selenium, zinc) may help restore balance.
