What is the Thyroid | Under-Active Thyroid & Over-Active Thyroid problems

What is the Thyroid?

What is the thyroid? Well your thyroid is what is known as an endocrine gland. It sits in the front of your neck and lies in a position just below your Adam’s apple.

Endocrine glands are the ductless glands of your endocrine system. These glands secrete their products 'hormones' directly into your blood. Through these hormones it produces, the thyroid gland then influences most of the metabolic processes within your body.

Your thyroid is made up of 2 lobes - the right lobe & the left lobe. Each lobe is about the size of a nectarine cut in half. These 2 lobes are then joined by a small bridge of thyroid tissue called the isthmus & lie on either side of your windpipe.

The thyroid hormone helps control the speed of your bodies metabolism. The faster your metabolic rate, the more calories your body burns at rest.

These hormones keep your body functioning at the correct speed. If your thyroid gland does not make enough hormones, then your bodies cells work slower than normal, and so things get out of kilter.

Your endocrine system makes hormones that help control the way your body functions. Your thyroid gland makes the following 3 hormones:

Thyroid disorders are very common & anybody of all ages can be affected. However, thyroid issues tend to occur more in women than men.

About 1 in 20 people has some kind of thyroid disorder, which may be temporary or permanent. Thyroid disorders can range from a harmless issue like a thyroid on neck, up to a more serious issue like thyroid cancer. A thyroid blood work test will determine any unusual signs underactive thyroid or overactive.

In this article we will examine what is underactive thyroid symptoms, types, diagnosis & thyroid treatments. Then finally its impact & how these may all affect terms for life insurance, critical illness, income protection & private health insurance.

What are causes of Thyroid Problems?

So what are causes of thyroid problems? Well, let's look at the 2 main types of symptoms thyroid problems (thyroid hypo or hyper).

  • Hypo thyroidism = Under-active thyroid'
  • Hyper thyroidism = 'Over-active thyroid'

Under-Active Thyroid Symptom | 'Hypo thyroidism' Autoimmune

What is an underactive thyroid or 'Hypo thyroidism'. The medical causes originate from an under-production of your thyroid hormones thyroxine (also called T4). Your bodies energy production requires certain amounts of these thyroid hormones. Any drop in your hormone production then leads to lower energy levels ie; not enough thyroxine is produced for your bodies needs.

Causes of underactive thyroid (hypo thyroidism) are via your bodies immune systems (which usually fights infection) now instead attacking your thyroid gland, and then damaging it. This means it is then not able to make enough of the hormones so reducing your thyroxine role. Viral Infections & some medicines can also cause signs of underactive thyroid.

Untreated for long periods of time, hypo thyroidism can bring on a a rare but potentially fatal thyroid condition called a myxedema coma (this requires immediate hormone treatment). There are several conditions when testing thyroid function, that may cause an under-active thyroid.

* Hypothyroidism Hashimoto | Immune System

Hypothyroidism hashimoto disease is the most common type of autoimmune disorder reaction that causes makes your thyroid under-active. Thyroid hashimoto appears to run in families (familial or hereditary), but it's not clear what causes this thyroid disease hashimoto. It's also common in people with other immune system disorders, such as type 1 diabetes and vitiligo.

* Removal of the Thyroid

Removal of the thyroid or Thyroidectomy is the surgical removal of all or part of your thyroid gland. However, an underactive thyroid can still occur as side effects or complications of the removed thyroid or previous thyroid treatments.

You can also have a thyroid surgical treatment called radioactive iodine therapy. Surgery & removal by a thyroid endocrinologist specialist is the sometimes the recommended treatment for several disorders of the thyroid gland.

* Hypothyroidism Lithium | Under Active Thyroid Symptom

Many common medication drugs can affect thyroid functions, so your GP will then need to checkout the cause of underactive thyroid. One in particular is Lithium, a medication often used for the treatment of mood disorders, including bipolar disorder. However, it is also associated with an increased risk of hypothyroidism, known as Hypothyroidism Lithium.

* Hypothyroidism Goitre | Thyroid on Neck

Hypothyroidism goitre is an enlarged thyroid on neck or multi-nodular goitre. This may cause obstructive symptoms of breathing or swallowing difficulties. Sometimes this can also lead to both 'underactive thyroid symptoms' & what are overactive thyroid symptoms.

If your GP thinks you have a hypothyroidism goitre, they will examine your thyroid on neck to check if your thyroid gland is swollen. Thyroid symptoms neck nodules are lumps or swellings in the thyroid gland & most are harmless. Either way don't leave it to chance & check in case the goitre thyroid symptoms are among the few that are cancerous.

They may also request a underactive thyroid nhs symptoms test - to see how well your thyroid functions are working.

Hypothyroidism & Under Active Thyroid Symptoms

* Hypothyroidism Iodine Deficiency | Iodine in Hypothyroidism

Iodine in Hypothyroidism is one element that plays a crucial role & causal factor if symptoms for low thyroid are deficient. Goitre iodine deficiency occurs when you are not having sufficient iodine in food & diet.

The body does not make iodine, so it is an essential part of a balanced diet. Iodine is found in various foods but to prevent iodine deficiency in past history, the introduction of iodized salt virtually eliminated iodine deficiency in Europe.

* Hypothyroidism with Pregnancy

Several traits of what is underactive thyroid symptoms are similar to Hypothyroidism with Pregnancy. For example, when pregnant you may get extra weight gain, more fatigue, or abnormal menstruations, which are common to both conditions.

In pregnancy thyroid issues are usually caused by thyroid hashimoto, the autoimmune disorder. During pregnancy thyroid level are often mild for many women and so you may not have uncomfortable pregnant thyroid symptoms.

However, untreated pregnancy thyroid issues in more extreme female cases can lead to pre-eclampsia, anemia, miscarriage, low birth weight or even stillbirth.

* Hypothyroidism with Weight Loss

There is a complex biological relationship between thyroid disease, body weight & metabolism. Weight gained in hypothyroidism is due to a greater accumulation in water & salt. So, conversely once treated you can expect a small hypothyroidism with weight loss impact (upto 10% of body weight).

Thyroid hormones have been used in the post as a weight loss tool ie; hypothyroidism lose weight. Scientific studies have shown that excess thyroid hormone treatment can for some help produce more weight loss for thyroid underactive patients, than any success may be achieved by just dieting alone.

However, once any specialist excess thyroid hormone medication is stopped, the excess weight loss is usually regained, unless balanced against other hypothyroidism weight targeted activity. 


Over-Active Thyroid | Hyper Thyroidism

'Hyper thyroidism' Over-active Thyroid |  v Under Active Thyroid Symptom
Hyperthyroidism 8

'Hyperthyroidism' (overactive thyroid) causes originate from an over-production of 2 thyroid hormones; thyroxine (T4) & triiodothyronine (T3). An over-active thyroid can speed up your metabolism also causing unpleasant symptoms.

There are several conditions that may cause an over-active thyroid sometimes known as hyperthyroidism 8.

Is overactive thyroid dangerous? YES, if left untreated.

* Graves' Disease NHS | Graves' Disease Symptoms

Graves' disease NHS state is an autoimmune condition where your bodies immune system mistakenly attacks your thyroid which then causes it to become overactive. Graves' disease NHS state is the no 1 cause of 'hyper thyroidism', with 3 in every 4 people with an over-active thyroid gland.

The cause of Graves' disease NHS advise is unknown, but it seems to be triggered by a combination of genes or outside virus. It mostly affect younger or middle-aged women & can be familial (hereditary). Smoking can also increase your risks of having to then get graves' disease.

Radioiodine therapy is a common and effective graves' disease treatment which slowly destroys the cells of the thyroid gland that produce thyroid hormone.

Graves' disease symptoms are the same as symptoms for overactive thyroid.

* Thyroid Lumps | Thyroid Nodules Cause

Your can get an over-active thyroid if thyroid lumps (thyroid nodules) then develop on it thus causing it to swell.

Thyroid nodules are usually benign and non-cancerous. Thyroid Nodules cause maybe a simple overgrowth of normal thyroid tissue, fluid-filled cysts, inflammation (thyroiditis). Or it can be a tumor (either benign such as pituitary adenoma or cancerous thyroid) which can result in the production of excess thyroid hormones all leading to 'hyper thyroidism'.

The real thyroid nodules cause is not known why some people develop them, but they seem to mostly affect people over age 60.

* Iodine in the Thyroid | Iodine in food & medicine

Taking additional iodine in medicine supplements can cause your thyroid gland to produce too much hormones.

This is also known as iodine in hyperthyroidism (Jod-Basedow phenomenon). It usually only occurs if you already have nodules in your thyroid gland.

* Secondary Hyperthyroidism

Secondary hyperthyroidism is a less common variant and it may be due to hypothalamic or pituitary disease

The main cause of secondary hyperthyroidism is therefore failure of the pituitary gland to correctly secrete thyroid stimulating hormone (TSH).


What are Underactive Thyroid Symptoms?

Many 'under-active thyroid symptom' are the similar to those of other health conditions, so your GP may therefore initially confuse under active thyroid symptoms for something else.

Life Insurance Types | Under Active Thyroid Symptom

There are 2 main types of life insurance types for those with under-active thyroid symptoms in the UK Protection marketplace:

1] Term Insurance

Term Life Insurance is a simple plan that pays out a cash sum if you died during the fixed time period your policy runs for. The sum paid out on death insurance stays level for family lifecover or decreasing for mortgage protection.

The premiums usually remain level during the term, whether you are near the policy beginning or end. Most term plans also include free 'terminal illness' cover. You can choose options of Lump Sums or Family Income Benefits & also if you want your cover to be inflation proofed.

The longer any level term insurance runs, then the more expensive it costs ie; 40 years term maybe double or more the cost than 20 years, as the insurance risks are higher as you get older. Insurers may allow you to take a term insurance plan upto age 90.

2] Whole of Life Insurance

Whole of Life Insurance policy, always pays out if you die ie; whenever this happens (as long as you have kept up with monthly payments & T&C's). For someone with thyroid under-active issues, whole life insurance maybe the most expensive compared to term insurance, as it will always payout.

Note: Over 50's Lifecover asks no medical questions about any health issues of either 'hypo thyroidism' or 'hyperthyroidism'. It could always be a choice if you had say thyroid cancer life insurance that asks medical questions would be declined or too expensive, or you have other poor health issues.

Importance of Disclosure & Claims?

All Insurers are in business to protect, insure & payout. Life Insurance is therefore based on your full disclosure at the time you take the original policy out (even if it costs more for life insurance and underactive thyroid sufferers) ie; being 100% as honest & accurate as possible. It is not always easy to remember all your historic health details when applying.

The Consumer Insurance Act 2013 says you must not be acting careless, deliberate or reckless manner when applying. If so, it may not payout ! eg; If you have family history of diabetes or heart issues (even if you are okay currently) then you must tell them. Or, you forget to even advise you have under active thyroid asthma because it does not currently cause you any health problems.

Should you make a claim, your Insurers will send you a claim form for you to complete. Once received back, they will usually contact your GP to confirm any health details disclosed ie; underactive thyroid nhs symptoms confirmed on diagnosis.

They will then assess if your insurance claim is valid and cross check if you originally disclosed all the correct details - on your life insurance, income protection or critical illness claim.

What if my health changes after taking the policy out?

Any health or lifestyle changes since, usually does not void your existing life policy, if it wasn’t relevant at that time of initial underwritten insurance application. For example, you have thyroid issues diagnosed several years afterwards. In this instance, the insurers should not classify the original application for life insurance thyroid biased. It maybe the Insurers request GP reports when you originally apply, to check any health details disclosed. Likewise they may not.

So take care to doubly re-check on your application what you initially disclosed to the Insurers, as this information then stands now and in the future. Please check your original T&C’s.

Alternatively, if your own Insurers originally applied 'health rated terms' on hypothyroidism and life insurance, then it can be worth reviewing your application.
