Signs Your Thyroid Medication Dosage Is Too Low

Recognizing the Symptoms of Inadequate Thyroid Medication

Hypothyroidism, also known as an underactive thyroid, affects nearly 5% of people in the United States. It occurs when the thyroid gland does not produce enough thyroid hormones to meet the body's needs. Thyroid hormone plays an important role in regulating metabolism, growth, development, and mood.

Hypothyroidism is typically treated by replacing the missing hormones with oral thyroid medication, such as Synthroid or Levothyroxine. When first starting treatment, getting the thyroid medication dosage right can take some time and adjustment. It's important to recognize the signs that your dose may be too low so that you can consult your doctor about increasing it appropriately.

1. Persistent Symptoms of Hypothyroidism

If you continue experiencing hypothyroid symptoms like fatigue, weight gain, dry skin, hair loss, impaired memory and concentration, constipation, muscle cramps, and feeling cold even after starting thyroid medication, it likely means your dose is too low. The right thyroid hormone dosage should bring relief from most hypothyroid symptoms.

2. Elevated TSH Levels

Your doctor will monitor your thyroid health through regular TSH tests. TSH stands for thyroid stimulating hormone. If thyroid hormone levels are low, the pituitary gland releases more TSH to urge the thyroid to produce more hormones. High TSH indicates that thyroid levels are still inadequate. If your TSH remains elevated out of the normal range while on medication, increasing the dosage is often necessary.

3. Persistent Cholesterol Problems

Since thyroid hormones impact lipid metabolism, persistently high LDL cholesterol and triglycerides along with low HDL cholesterol, may indicate a low thyroid medication dose. Getting thyroid levels optimized helps regulate cholesterol markers.

Dangers of Persistently Low Thyroid Hormone Levels

Letting hypothyroidism go untreated, or failing to control it adequately with medication, allows the signs and symptoms to progress and leads to several harmful effects throughout the body over time.

Impaired Heart Health

The low metabolism caused by hypothyroidism allows LDL cholesterol to accumulate in blood vessels. This raises the risk for atherosclerosis, hypertension, and heart disease. Congestive heart failure becomes increasingly possible as the heart works harder to pump blood through narrowed vessels.

Reduced Fertility

Thyroid hormones maintain the function of the testes and ovaries. Low levels prevent the reproductive organs from getting the stimulation needed for producing sperm, eggs, and supporting hormones. Prolonged hypothyroidism often causes infertility issues.

Birth Defects

Untreated maternal hypothyroidism early in pregnancy gets associated with a higher chance of birth defects. Poor thyroid function impairs baby’s brain and nervous system development.

Peripheral Neuropathy

Without enough thyroid hormone regulation, tissues don’t get the energy they require. Over time, nerves become damaged from the chronic lack of metabolism. This leads to numbness, tingling, weakness, and pain through the extremities.

Mental Health Disorders

Hypothyroidism stands linked to psychiatric problems like depression and bipolar disorder. The thyroid influences neurotransmitter balance and function. Thyroid hormone deficiencies contribute to altered mood, motivation, concentration, and cognition as brain cell metabolism suffers.

Safely Increasing Your Thyroid Medication Dosage

If you display persistent signs that your thyroid medication dose gets administered at too low a level, consult your doctor promptly. Getting accurate TSH testing done while discussing your lingering symptoms will help verify if an adjustment is necessary.

Gradual Dose Increases

Finding the optimal dose usually requires small, gradual increases over weeks or months. Jumping substantially or ramping up too quickly presents more risk of side effects. Patience pays off to reach adequate control of hypothyroidism.

Allow Time for Improvement

It takes several weeks after each dosage change for your TSH and low thyroid symptoms to stabilize based on the adjustment. Have follow-up thyroid lab tests and let your body respond before making conclusions about the effectiveness of an increased medication dose.

Monitor for Hyperthyroidism

Too high a thyroid hormone dose leads to hyperthyroidism, an overactive thyroid state involving sudden weight loss, rapid heart rate, anxiety, tremors, frequent bowel movements, and sleeping difficulty. Keep an eye out for signs of too much medication as your doctor tweaks your prescription upwards.

Achieving optimal thyroid hormone levels through properly dosed medication prevents hypothyroid complications and helps you feel your best day-to-day. Tracking your symptoms and getting the right blood tests provide valuable insight over time as your levothyroxine requirements may change. With competent medical care and self-monitoring, living well with hypothyroidism proves fully possible through consistent, adequate thyroid replacement therapy.
