Hypothyroidism affects 2% of adult women and causes fatigue, hair loss, and unexplained weight gain. It is diagnosed with a simple TSH test and is treatable.
Symptoms of an underactive thyroid (hypothyroidism) include extreme fatigue upon waking, noticeable hair loss, unexplained weight gain, constant chills, and brain fog. It is diagnosed with a simple TSH blood test. The most scientifically supported treatments for hypothyroidism are selenium (which reduces antibodies in Hashimoto’s thyroiditis according to a 2025 meta-analysis of 1,610 patients), iodine in adequate amounts, reducing chronic stress, and getting enough sleep. If TSH levels are significantly elevated, medication is necessary.
You say goodbye and you’re already tired. Your hair falls out when you wash it. You’ve gained weight without doing anything different. And nobody tells you why.
There’s a gland in your neck that’s probably malfunctioning. It’s called the thyroid. And hardly anyone checks it until everything’s ruined.
The thyroid is small—about the size of a butterfly. But it controls EVERYTHING: your metabolism, your energy, your body temperature, your mood, your digestion.
When it malfunctions, your body cries out for help. But most people don’t understand what they’re hearing.
What Is the Thyroid (Explained Simply)
Your thyroid is a gland in your neck, below your Adam’s apple. Its job: to produce thyroid hormones—your body’s “accelerator.” They control how fast everything works.
When your thyroid produces the RIGHT amount, your body functions perfectly. When it produces TOO LITTLE ( hypothyroidism ), your body slows down: low energy, weight gain, and low mood. When it produces TOO MUCH ( hyperthyroidism ), your body speeds up: anxiety, palpitations, and rapid weight loss.
Both are problems. And both have solutions.
Thyroid: Symptoms of Hypothyroidism and Hyperthyroidism, Remedies and Evidence
Symptom / Remedy Guy Applies to Scientific evidence
Extreme tiredness (sleeps 10 hours and is still tired) ⚠️ Symptom Hypothyroidism High — MSD Manual, Mayo Clinic 2024
Weight gain without changing your diet ⚠️ Symptom Hypothyroidism High — metabolism drops to up to 30% fewer calories
Hair loss and dry skin ⚠️ Symptom Hypothyroidism High — CUN, Merck Manuals 2024
Constant cold (when others are comfortable) ⚠️ Symptom Hypothyroidism Stop — MSD Manual 2024
Depression, sadness, or a clouded mind ⚠️ Symptom Hypothyroidism High — directly affects neurotransmitters
Palpitations, tremors, and extreme anxiety ⚠️ Symptom Hyperthyroidism Stop — Merck Manuals 2024
Rapid weight loss without dieting ⚠️ Symptom Hyperthyroidism High — metabolism accelerates 40%+ more
Selenium 200 mcg/day ✅ Remedy Hypothyroidism (Hashimoto’s) Very high — 2025 meta-analysis (21 studies, 1,610 patients): significantly reduces TPOAb at 3 and 6 months
Adequate iodine (iodized salt, fish, dairy products) ✅ Remedy Hypothyroidism due to deficiency Stop — ATA 2024 (caution: excess is harmful in Hashimoto’s)
Chronic stress reduction ✅ Remedy Both (aggravates both) Moderate-high — cortisol suppresses thyroid function
Quality sleep (8 hours minimum) ✅ Remedy Both Moderate — the thyroid regenerates during deep sleep
Raw cruciferous vegetables (broccoli, cabbage, cauliflower) ✅ Remedy Hyperthyroidism Moderate — interfere with iodine absorption, slow down overactive thyroid
Levothyroxine (doctor) ✅ Medical treatment Clinical hypothyroidism Very high — standard treatment, one pill daily, safe long-term
Hypothyroidism: Underactive Thyroid (Most Common)
Hypothyroidism affects 2% of adult women compared to 0.1-0.2% of men, and its incidence increases after age 40-50 . Your thyroid gland doesn’t produce enough hormone. Your body slows down in every way.
