Thyroid Disorders: Symptoms, Diagnosis and Treatment

• Thyroxine (T4): This is the inactive form, which is converted to the active hormone.
• Triiodothyronine (T3): The active form which directly impacts metabolism, heart rate, and body temperature.

• Unexplained Weight Gain: The slower metabolism means you could gain weight even when eating normally.
• Extreme Fatigue: No matter how much sleep you get, the feeling of tiredness surrounds you 24/7.
• Cold Sensitive: You feel cold even in warm conditions.
• Depression & Brain Fog: “The most common one is difficulty concentrating and low mood.
• Constipation: Slow digestion is an underappreciated symptom.
• Hair Loss & Dry Skin: Your hair might turn brittle or fall out; your skin may feel dry. 

• Unexplained Weight Loss: You start to lose a lot of weight because your metabolism makes your process fireup.
• Heart Palpitations & Anxiety: Rapid pulse rate and nervousness are typical symptoms.
• Heat Sensitivity & Sweating: You may feel hot in normal temperatures.
• Loose Stools: Digestion is accelerated, resulting in increased bathroom visits.
• Tremors & Muscle Weakness: Hands may shake or feel weak.
• Bulging Eyes (Graves’ Disease): This is a classic sign of an overactive thyroid. 

• Women over 35
• Pregnant women
• Individuals with a family history of thyroid disorders
• Anyone experiencing unexplained weight changes, fatigue or mood swings
• People with autoimmune diseases such as diabetes or rheumatoid arthritis 

• Hypothyroidism: Typically managed with levothyroxine, a synthetic thyroid hormone.
• Hyperthyroidism: Treated with antithyroid drugs, radioactive iodine therapy, or surgery for severe cases.
• Diet & Lifestyle Adjustments: Foods high in iodine, selenium and/or zinc essential for thyroid function

1. Thyroid Disorders Munchausen Other Conditions
   Thyroid imbalances also often mimic other health concerns, like depression, anxiety, menopause, or even cardiac concerns. This can contribute to misdiagnosis and unnecessary therapies.
   For instance, an underactive thyroid (hypothyroidism) can cause slow heart rate and fatigue, which may mimic heart disease. Hypertension (high blood pressure) and hyperthyroidism (overactive thyroid) can also produce anxiety-like symptoms and lead to unwarranted psychiatric treatments.
   
   
2. Some Medications Can Interfere With Your Thyroid 
   Many common medications can upset thyroid function, such as:
   • Beta-blockers (for high blood pressure) – can suppress thyroid hormons.
   • Lithium (for bipolar disorder) — a known inducer of hypothyroidism.
   • Hormonal contraceptives and estrogen therapy– may change thyroid function, and medication adjustments are needed.
     
     If you take these drugs, you need regular thyroid screenings.
3. Your Digestive Health Is Linked to Your Thyroid
   Newer research suggests gut bacteria convert thyroid hormones. An unhealthy gut also diminishes the body's ability to absorb and use thyroid hormones effectively. This is why those with thyroid disorders do well on:
   • PROBIOTICS (yogurt, kimchi, kefir)
   • High fibre foods (e.g. vegetables and whole grains)
   • Balanced diets and hydration
4. Lifestyle Choices Can Impact Thyroid Function
   Your thyroid can be impacted by chronic stress, lack of sleep and extreme dieting. The stress hormone cortisol suppresses thyroid function, causing fatigue and weight gain. Crash diets or dramatically cutting calories can also slow metabolism and worsen symptoms, particularly in patients with hypothyroidism.
5. Thyroid Disorders May Impact Fertility and Pregnancy
   Thyroid hormones are important in reproductive health. Untreated thyroid imbalances may prevent conception or raise the likelihood of miscarriage. Pregnant women with hypothyroidism are at increased risk for preterm birth and their babies may develop problems.

So if you are trying to conceive, a thyroid function test (TFT) is essential.
