Is Synthroid For High Or Low Thyroid

How Do I Know If I Have Hypothyroidism

Levothyroxine or Armour Thyroid for Hypothyroidism (Low Thyroid Symptoms)

With Hashimotos thyroiditis, the onset of symptoms is usually very gradual, evolving over months to years. Usually the disease is detected when the patients symptoms are mild, before any profound changes develop. Many people are diagnosed by a blood test before they are even symptomatic. When symptoms do develop, they commonly include low energy, weight gain, intolerance to cold, muscle aches, joint aches, and constipation. Women may note a change in their menstrual periods.

More advanced symptoms include a slowed heart rate, low body temperature, and changes in the skin and nails . The lateral portions of the eyebrows may thin and there may be swelling of the tissues around the eyes.

Rarely, under stress such as a severe acute illness, patients with untreated or inadequately treated hypothyroidism may develop a severe condition called myxedema coma. Often occurring in hypothyroid patients exposed to cold or an infection, these patients experience hypothermia, hallucinations, severe swelling, and slow heart rate. This is a potentially life-threatening condition that must be treated in an intensive care unit.

What Other Foods Should You Avoid When Taking Synthroid

Even if youre not a coffee drinker, there are certain things that can affect how well Synthroid works. According to DailyMed, the following foods can make it harder for your body to absorb Synthroid:

  • Walnuts
  • Cottonseed meal
  • Dietary fiber

Maintaining Healthy Blood Sugar Levels

Both high and low blood sugar levels are potentially harmful to your health, which is why it is mandatory to keep them within a healthy range.

This is particularly important if you have hypothyroidism, thyroid disorder associated with weight gain, high cholesterol, and other symptoms affecting your heart health.

Below, youll find useful tips that will help you maintain healthy blood sugar levels:

Low Thyroid & High Cholesterol

One measurement of thyroid function is a hormone called thyroid-stimulating hormone . Made by a small gland at the base of the brain called the pituitary, TSH tells your thyroid how hard to work.

High TSH levels mean you have an underactive thyroid. Symptoms include:

  • Fatigue
  • Weight gain
  • Slow heart rate

Studies show that people with high TSH levels have much higher total cholesterol and LDL levels than people with normal thyroid tests.

Any of these can be fatal.

High cholesterol raises heart disease and stroke risk even more.

What To Expect When Starting Synthroid

When you first start taking Synthroid, your doctor will usually test your TSH levelsi every 6 to 8 weeks. Try to be patient during this time. Because your thyroid hormone needs are very precise, your doctor may need to make small adjustments to find the dose thats right for you. And it may take several weeks before you notice Synthroid is working, and for your thyroid levels to adjust to the correct range.

What If I Miss A Dose

If you miss a dose of Synthroid, take it as soon as you remember. But if its close to the time of your next dose, skip the missed dose and take your next scheduled dose as usual. If you arent sure whether to take the missed dose or skip it, talk with your doctor or pharmacist.

Do not double up on Synthroid doses to make up for a missed dose. Doing this can increase your risk for side effects from the drug.

If you need help remembering to take your dose of Synthroid on time, try using a medication reminder. This can include setting an alarm, downloading a reminder app, or setting a timer on your phone. A kitchen timer can work, too.

Dont use more Synthroid than your doctor prescribes. Using more than this can lead to serious side effects, likely due to hyperthyroidism .

How Tsh Levels Change

TSH levels are not very intuitive. Why does a high TSH mean you have an underactive thyroid gland? Why do low levels means the gland is overactive?

Understanding exactly how the thyroid gland works can help.

Your thyroid gland produces thyroid hormone. When it functions properly, your thyroid is part of a feedback loop with your pituitary gland that involves several actions:

First, your pituitary gland senses the level of thyroid hormone that is released into the bloodstream.

Your pituitary then releases the special messenger hormone TSH, which makes the thyroid release more thyroid hormone. From there:

  • If your thyroid doesn’t produce enough thyroid hormone, your pituitary triggers your thyroid to make more.
  • If your thyroid is overactive and producing too much thyroid hormone, your pituitary senses that and slows or shuts down TSH production.

Side Effects Of Too Much Levothyroxine

One potential effect of too much levothyroxine that might seem nice is weight loss, but over-replacement with thyroid therapy so your TSH levels become too low is a bad ideaand I see it all the time.

The main risk is atrial fibrillation, a dangerous heart rate abnormality, which occurs three times more often in patients who are on too much levothyroxine. You may also have accelerated bone loss and therefore, a higher risk of fractures.

Why Is This Medication Prescribed

Thyroid Medications (Synthroid VS Armour)

Levothyroxine is used to treat hypothyroidism . It is also used with surgery and radioactive iodine therapy to treat thyroid cancer. Levothyroxine is in a class of medications called hormones. It works by replacing thyroid hormone that is normally produced by the body.

Without thyroid hormone, your body cannot function properly, which may result in poor growth, slow speech, lack of energy, excessive tiredness, constipation, weight gain, hair loss, dry, thick skin, increased sensitivity to cold, joint and muscle pain, heavy or irregular menstrual periods, and depression. When taken correctly, levothyroxine reverses these symptoms.

Signs And Symptoms Of Overmedication

Signs and symptoms of thyroid hormone overmedication can vary, but some common ones include:

  • Elevated pulse and blood pressure
  • Anxiety, nervous energy, tremors
  • Feeling like your heart is skipping a beat or racing
  • Weight loss with no change in your diet/exercise routine
  • Increase in food intake with no weight gain

In some cases, symptoms of overmedication can be similar to those of hypothyroidism. You may feel more exhausted than usual, or achy and as if you have the flu you may put on weight, or feel jittery and anxious.

In fact, it’s not unheard of for a person to visit their healthcare provider to get tested, certain that they need an increased dosage, only to discover that their symptoms are actually due to overmedication.

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your response to thyroid.
