An overactive thyroid (hyperthyroidism) can cause a number of symptoms, which include mood swings, anxiety, nervousness and irritability, persistent tiredness and weakness, sensitivity to heat, swelling in the neck from an enlarged thyroid gland, weight loss, trembling or twitching, and an irregular or unusually fast heart rate. In the case of an underactive thyroid (hypothyroidism), symptoms may involve fatigue, constipation, dry skin, weight gain, increased sensitivity to cold, muscle weakness, hoarseness, elevated cholesterol level, pain, stiffness or swelling in the joints, thinning hair, depression, slower heart rate, and impaired memory. Hashimoto’s thyroiditis is known as the most common cause of hypothyroidism in the USA, affecting almost 14 million people. It’s mostly common in middle-aged women and symptoms include: mild weight-gain, dry skin, pale or puffy face, enlarged thyroid, intolerance to the cold, heave and irregular menstruation, fatigue, and depression. Make sure you see your doctor if you have any of these symptoms. Thyroid disease management is important. Never avoid contracting a doctor; if you think you have an issue with your thyroid, get it checked now to avoid further complications to your health down the road.
