SIGNS THAT YOU HAVE A LOW THYROID LEVEL – Hypothyroidism Symptoms

If you’re suddenly pitting out, that’s not a good sign.

If you’ve never paid attention to your thyroid, put your hand on the front of your throat and swallow.

The bump that moves is the cartilage often called the Adam’s apple, and underneath that is where your thyroid sits. Your thyroid is basically the on-board computer for your bodythe hormones it regulates affect almost every system and as long as it’s doing its job you forget it’s even there. But when it’s not working properly? Hell, meet hand basket.

When the thyroid doesn’t produce enough hormone, it’s called hypothyroidism, which can lead to symptoms like weight gain, fatigue, irregular periods, or a slowed heart rate.

The most popular medication used to to treat hypothyroidism and bump up those hormone levels: Synthroid.

Synthroid is the brand name for levothyroxine sodium, a synthetic thyroid hormone pill. “Even though Synthroid is a lab-created hormone it’s identical to the kind produced naturally in the body,” says Melanie Goldfarb, M.D., an endocrinologist and thyroid specialist at Providence Saint John’s Health Center in Santa Monica, California. “Taking Synthroid replaces the hormones that your thyroid should be making but, for whatever reason, isn’t.”

Although there are about 1 percent of patients that won’t respond to Synthroid at all and will need other treatment, the vast majority of people on it feel remarkably better within six weeks of starting it, she adds.

Causes Of An Underactive Thyroid

An underactive thyroid is when your thyroid gland doesn’t produce enough of the hormone thyroxine .

Most cases of an underactive thyroid are caused by the immune system attacking the thyroid gland and damaging it, or by damage that occurs as a result of treatments for thyroid cancer or an overactive thyroid.

Will I Have The Same Dose Of Medication For Hypothyroidism My Entire Life

The dose of your medication can actually change over time. At different points in your life, you may need to have the amounts of medication changed so that it manages your symptoms. This could happen because of things like weight gain or weight loss. Your levels will need to be monitored throughout your life to make sure your medication is working correctly.

  • Thyroid surgery: If you had part of your thyroid removed, whats left might not be able to make enough hormones for your body.

  • History of hyperthyroidism: Previous treatment for too much thyroid hormone can leave you without enough. Also, an overactive thyroid can burn itself out and then be unable to keep up.

  • Radiation to the area: Radiation for treatment of head and neck cancers can hurt the thyroid gland as a side effect. The same radiation beams that kill the cancer cells can also damage the bodys normal tissues.

  • Family history: You have a higher chance of having hypothyroidism if your family members have it specifically close family members like parents, grandparents, or siblings.

    How Is The Proper Dose Determined

    All dogs are started on a standard dose of thyroid replacement hormone, based on the dog’s weight. After one month of treatment, a blood sample is taken to verify that the thyroid hormone levels are normal. The blood sample is usually taken just before or 4-6 hours after medication administration as hormone levels can fluctuate.

    “Since the dog’s tolerance of the thyroid replacement hormone may change over time, the dose may need to periodically adjusted.”

    Since the dog’s tolerance of the thyroid replacement hormone may change over time, the dose may need to be periodically adjusted. It is usually necessary to retest thyroid hormone levels every six months. Close communication with your veterinarian is necessary in order to ensure that your dog is neither over- nor under-dosed. It is also important to monitor your dogs condition. If signs of hypothyroidism recur or if you feel your dog has signs of hyperthyroidism discussed below, let your veterinarian know right away.

    Trouble Concentrating Or Remembering

    Synthroid Overdose: signs you taking too much thyroid medication

    Many patients with hypothyroidism complain of mental fogginess and trouble concentrating. The way this mental fogginess presents itself varies by person.

    In one study, 22% of low-thyroid individuals described increased difficulty doing everyday math, 36% described thinking more slowly than usual and 39% reported having a poorer memory .

    In another study of 14 men and women with untreated hypothyroidism, the participants showed difficulty remembering verbal cues .

    The causes for this are not yet fully understood, but difficulties in memory improve with treatment of low thyroid hormone .

    Difficulties in memory or concentration can happen to everyone, but if they are sudden or severe, they could be a signal of hypothyroidism.

    Summary: Hypothyroidism can cause mental fogginess and difficulty concentrating. It may also impair certain kinds of memory.

    Whats The Difference Between Hypothyroidism And Hyperthyroidism

    In hypothyroidism, the thyroid doesnt make enough thyroid hormone.

    The difference between hypothyroidism and hyperthyroidism is quantity. In hypothyroidism, the thyroid makes very little thyroid hormone. On the flip side, someone with hyperthyroidism has a thyroid that makes too much thyroid hormone. Hyperthyroidism involves higher levels of thyroid hormones, which makes your metabolism speed up. If you have hypothyroidism, your metabolism slows down.

    Many things are the opposite between these two conditions. If you have hypothyroidism, you may have a difficult time dealing with the cold. If you have hyperthyroidism, you may not handle the heat. They are opposite extremes of thyroid function. Ideally, you should be in the middle. Treatments for both of these conditions work to get your thyroid function as close to that middle ground as possible.

    What Is The Thyroid And What Does It Do

    The thyroid is a small, butterfly-shaped gland in the front of your neck. It is a thyroid hormone factory! Thyroid hormones control everything your body temperature, heart rate, blood pressure, metabolism, weight. They even affect how your skin, hair, and nails behave.

    Your thyroid gland takes iodine from your blood to make the hormone thyroxine or T4. The 4 is because it has four iodine molecules. Another thyroid hormone is T3 with three iodine molecules. More on the iodine later.

    Your thyroid is in constant communication with your brain. Your brain sends out a signal called thyroid stimulating hormone . TSH tells the thyroid when the factory needs to up its production. When the body has enough thyroid hormone, the brain relaxes. It sends out less TSH telling the thyroid to make less hormones. Hows that for teamwork?

    Can You Switch From Levothyroxine To Armour Thyroid

    Transferring from levothyroxine to Armour requires dose adjustments. If you are switching from levothyroxine or Synthroid over to Armour thyroid then you must consider how to adjust your dose during the transition. Unfortunately, its not as easy as just saying well, Im taking 100mcg of levothyroxine so I will need 100mg of Armour thyroid.

    Sometimes, a nodule or goiter just sits there and isnât dangerous.

    When they do cause problems, it could be something like:

    Cysts, fluid-filled nodules that can give you neck pain or make it hard to swallow. Theyâre very rarely cancer but still might need treatment.

    Gravesâ disease, which causes your thyroid to grow and make too many hormones.

    Hashimotoâs disease, where your thyroid is damaged by your immune system, so it makes fewer hormones than normal and then swells.

    Infection, where a virus causes pain and swelling in your thyroid.

    Large nodules or goiters that are an issue because of their size. They can push into surrounding body parts and make it harder to breathe or swallow.

    Toxic nodules or goiters, which are almost never cancer, can cause your thyroid to pump out too many hormones.

    Cancer, which makes up about 10% of cases.

    The thyroid is a small gland below the skin and muscles at the front of the neck, at the spot where a bow tie would rest.

    It’s brownish red, with left and right halves that look like a butterfly’s wings. It weighs less than an ounce, but helps the body do many things, such as get energy from food, grow, and go through sexual development. In younger children, it is also important for brain development.

    How Is It Diagnosed

    The most common screening test is a total thyroxin level. This is a measurement of the main thyroid hormone in a blood sample. A low level of total thyroxin, along with the presence of clinical signs is suggestive of hypothyroidism. Definitive diagnosis is then made by performing a free T4 by equilibrium dialysis or a thyroid panel that assesses the levels of multiple forms of thyroxin. If this test is low, then your dog has hypothyroidism. Some pets will have a low TT4 and normal free T4 by ED. These dogs do not have hypothyroidism. Additional tests may be necessary based on your pet’s condition. See handout Thyroid Hormone Testing in Dogs for more information.

    What Happens If Your Thyroid Is Out Of Balance

      If your thyroid gland isnt working quite right, this could lead to lots of problems. Your thyroid produces important hormones that regulate many functions in your body.

      What Are The Symptoms Of Hypothyroidism

      Hypothyroidism has many symptoms that can vary from person to person. Some common symptoms of hypothyroidism include

      • fatigue
      • thyroiditis, or inflammation of the thyroid
      • congenital hypothyroidism, or hypothyroidism that is present at birth
      • surgical removal of part or all of the thyroid
      • radiation treatment of the thyroid
      • some medicines

      Less often, hypothyroidism is caused by too much or too little iodine in the diet or by disorders of the pituitary gland or hypothalamus.1 Iodine deficiency, however, is extremely rare in the United States.

      When surgeons remove part of the thyroid, the remaining part may produce normal amounts of thyroid hormone. But some people who have this surgery may develop hypothyroidism. Removing the entire thyroid always results in hypothyroidism.

      Surgeons may remove part or all of the thyroid as a treatment for

      • hyperthyroidism
      • a large goiter
      • thyroid nodules, which are noncancerous tumors or lumps in the thyroid that can produce too much thyroid hormone
      • small thyroid cancers

      What To Expect If You Stop Taking Your Medication

      What should you expect if you stop taking your thyroid medication?

      The first thing you should realize is that you are most likely going to feel worse for a short period of time even if your body doesnt need thyroid medication.

      The reason for this is simple:

      Once you start taking thyroid medication it causes a negative feedback loop in your brain which REDUCES the amount of thyroid hormone that your thyroid gland produces naturally.

      This is a natural and healthy mechanism which is put in place by your body to prevent too much thyroid hormone from being produced.

      But the problem is your body doesnt necessarily know the difference between thyroid medication that you take by mouth or thyroid hormone that your thyroid gland produces naturally.

      So once it sees any thyroid hormone it alters the signals that it sends to your thyroid gland by lowering the TSH.

      The more thyroid medication you take by mouth the lower your TSH will get.

      So, as you stop taking your thyroid medication, its only natural that this TSH will start to increase.

      But you have to be aware of one major important point.

      Once your TSH has been artificially lowered with thyroid medications, it takes time for your brain and pituitary system to get back to full strength.

      In fact, it can take several weeks to months for it to get back to the normal state you were in prior to taking thyroid medication.

      This by itself isnt a reason to think that you HAVE to be on thyroid medication, however.

      How Do I Know If I Have Hypothyroidism

      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.
