Can Thyroid Cancer Cause Fatigue

Can Hyperthyroidism Be A Thyroid Cancer Symptom

Hyperthyroidism is not considered to be one of the primary symptoms of thyroid cancer, although some studies suggest that up to 20 percent of people with thyroid cancer might also have hyperthyroidism. Hyperthyroidism occurs when the thyroid gland overproduces a hormone called thyroxine. This can lead to fatigue, unexpected weight loss, heart palpitations, mood swings, sleep disturbances and other similar complications.

Do They Go Away On Their Own

According to an ATA study, thyroid nodules that occur due to iodine deficiency may resolve on their own over time if people increase their iodine intake. In 618 participants with thyroid nodules, roughly one-third of single nodules were no longer present at the 11-year follow-up.

The researchers concluded that increasing iodine intake through iodized salt might be the reason for the disappearance of the nodules.

In other cases, benign thyroid nodules may grow larger over time, and people may need treatment to remove them.

How Is Hyperthyroidism Diagnosed

Early detection is important so that you and your doctor can outline a plan for hyperthyroidism treatment before it causes irreversible damage. Brenessa Lindeman, MD, Assistant Professor of Surgery and Medical Education at the University of Alabama at Birmingham, emphasizes the need for people with suspicious symptoms to advocate for their own health and get checked for hyperthyroidism early to prevent serious complications like osteoporosis, premature menopause, or even cardiac arrest.

Methods of diagnosis for hyperthyroidism include:

• Analysis of medical history and symptoms
• Physical examination
• An ultrasound or nuclear medicine scan of your thyroid to see if it has nodules, or to determine whether it is inflamed or overactive
• Blood tests to measure levels of thyroid hormones and related substances, including thyroid stimulating hormone , triiodothyronine , thyroxine , and thyroid peroxidase antibody

Can A Dietitian Help Me Fight Cancer Fatigue

Dietitians can provide suggestions to work around any symptoms that may be interfering with caloric intake. They can help you find ways to take in calories despite an early feeling of fullness, swallowing difficulty or taste changes. Dietitians can also suggest ways of maximizing calories and proteins in smaller amounts of food. They may suggest powdered milk, instant breakfast drinks and other commercial supplements or food additives.

Thyroid Nodules Are Common But Usually Are Not Cancer

Your doctor may find a lump in your thyroid during a routine medical exam. A thyroid nodule is an abnormal growth of thyroid cells in the thyroid. Nodules may be solid or fluid-filled.

When a thyroid nodule is found, an ultrasound of the thyroid and a fine-needle aspiration biopsy are often done to check for signs of cancer. Blood tests to check thyroid hormone levels and for antithyroid antibodies in the blood may also be done to check for other types of thyroid disease.

Thyroid nodules usually dont cause symptoms or need treatment. Sometimes the thyroid nodules become large enough that it is hard to swallow or breathe and more tests and treatment are needed. Only a small number of thyroid nodules are diagnosed as cancer.

Musculoskeletal Symptoms Of Medullary Thyroid Cancer In Children

The musculoskeletal symptoms of medullary thyroid cancer in children include pes cavus, spine abnormalities, and bone pain due to the presence of bone lesions.6

A study that analyzed 79 children with either MEN1 or MEN2 found that calcitonin levels higher than 40 pg/mL were associated with an increased risk of medullary thyroid cancer and that almost half of children who had a thyroidectomy were beyond the age recommended by the American Thyroid Association 2009 guidelines. Their calcium levels were below normal, and half of them required treatment for hypocalcemia.7

Hyperparathyroidism is another symptom of familial medullary thyroid cancer, with 30% of patients with MEN2A developing hyperparathyroidism at a mean age of 33.7 years.8

Types Of Thyroid Cancer

There are 4 main types of thyroid cancer. They are:

• papillary carcinoma this is the most common type, accounting for about 6 out of 10 cases it usually affects people under the age of 40, particularly women
• follicular carcinoma accounts for around 3 out of 20 cases of thyroid cancer and tends to affect older adults
• medullary thyroid carcinoma accounts for between 5 and 8 out of every 100 diagnosed cases unlike the other types of thyroid cancer, medullary thyroid carcinoma can run in families
• anaplastic thyroid carcinoma this is the rarest and most aggressive type of thyroid cancer, accounting for less than 1 in 20 thyroid cancers it usually affects older people over the age of 60

Papillary and follicular carcinomas are sometimes known as differentiated thyroid cancers, and they’re often treated in the same way.

Why Do Some People With Hypothyroidism And Hashimotos Experience Weight Loss

Weight gain is common in those with hypothyroid conditions. And while most people with hypothyroidism and Hashimotos Thyroiditis have a difficult time losing weight, a small percentage of people with hypothyroid conditions find it challenging to gain weight. In this article I will discuss the common factors which cause some people with hypothyroidism and Hashimotos to experience weight loss and/or find it difficult to gain weight.

Before I talk about some of these causes, keep in mind that the focus of this article will be on those factors which can result in extreme weight loss. But what is considered to be extreme weight loss? Well, some sources consider a weight loss of greater than two pounds per week to be extreme. This is especially true if the weight loss occurs without dieting, but even if you are dieting it can be unhealthy to lose too much weight too fast. Other sources claim that losing over ten percent of your body weight in a period of 6 months is a cause for concern.

Are There Risks Of Losing Too Much Weight?

• Excessive loss of lean body mass
• Water and electrolyte problems
• Increased risk of forming gallstones
• Mild liver dysfunction
• Elevated uric acid levels

Weight Loss Cause #6: Inflammatory bowel disease. Both Crohns disease and ulcerative colitis can result in weight loss. The main reason for this is due to malabsorption.

Theyre likely to put off getting seen by a doctor and mayblame their symptoms on other causes.

Fatigue As A Symptom Of Hypothyroidism

Many symptoms of hypothyroid disease, including fatigue, commonly occur with other medical conditions, such as sleep apnea or anemia. For that reason, its important to determine if your fatigue is caused by hypothyroidism specifically or by another condition.

Taking into consideration all of your symptoms, your medical history, and the results of a physical exam, your health care provider can help you find the specific cause or causes for your fatigue.

According to the American Thyroid Association, approximately 20 million Americans have thyroid disease, although up to 60% of those may not know they have it. The American Association of Clinical Endocrinologists notes that more women have thyroid disease than men. Many of those affected by thyroid disease may have only very mild cases or symptoms.

For those with symptoms, fatigue often features at the top of the list. Other common symptoms include dry hair and skin, forgetfulness, a puffy face, and cold intolerance. Individuals with subclinical hypothyroidism may experience mild fatigue. Those with overt hypothyroidism often experience ongoing fatigue and other symptoms.

The most common cause of hypothyroidism, is an autoimmune condition in which thyroid antibodies attack the thyroid gland. It then becomes inflamed and unable to make enough thyroid hormone to support the bodys energy needs. Fatigue is a common symptom in those with Hashimotos thyroiditis.

Thyroid Hormone Replacement Therapy

Thyroid hormone replacement therapy is often prescribed after thyroid surgery to replace the hormones that are no longer being produced by your thyroid tissue. Depending on how much of your thyroid was taken out, you may have to take the medication most commonly levothyroxine for the rest of your life.

Thyroid hormone replacement can also help prevent the growth or recurrence of thyroid cancer. It does this by lowering your circulating level of the hormone TSH, which is secreted by your brains pituitary gland and tells your thyroid to make more thyroid hormone. High TSH levels can stimulate the growth of thyroid cancer cells. Higher doses of replacement thyroid hormone tell your body to make less TSH, slowing the growth of any thyroid cancer cells and lowering the odds of your cancer coming back.

It can take a few adjustments to find the correct dosage of thyroid hormone replacement. During this time, you may need to see the doctor every 6 to 8 weeks for a blood draw to determine if your levels are optimal.

Should I Change The Way I Eat To Combat Cancer Fatigue

Cancer fatigue may be worse if you’re not eating enough or if you are not eating the right foods. Maintaining good nutrition can help you feel better and have more energy. The following strategies can help you improve your nutritional intake.

• Basic calorie needs. A person with cancer whose weight has been stable needs about 15 calories per pound of weight each day. For example, a person who weighs 150 pounds needs about 2,250 calories per day to maintain weight. You should add 500 calories per day if you have lost weight.
• Protein rebuilds and repairs damaged body tissue. You need about 0.5-0.6 grams of protein per pound of body weight to rebuild and repair body tissue. For example, a 150-pound person needs 75 to 90 grams of protein per day. The best sources of protein include foods from the dairy group and meats .
• Fluid needs. Unless your healthcare provider tells you otherwise, you should aim for about 64 ounces per day to prevent dehydration. Fluids include juice, milk, broth, milkshakes, Jello® and other beverages. Of course, water is fine, too. Its important to note that beverages containing caffeine do NOT count. And if you are losing fluid from excessive vomiting or diarrhea, you will need extra fluids.
• Supplemental vitamins. Talk with your healthcare provider to find out if vitamin supplements are a good idea for you. Vitamin supplements don’t provide calories, which are essential for energy production. So vitamins cannot substitute for adequate food intake.

Even though the thyroid cancer may not be very large, it may still produce symptoms of pressure or sometimes even a tight or strangling sensation in the neck. This thyroid cancer symptom of pressure may seem disproportional to the size of the thyroid cancer itself. The explanation of this pressure or strangling sensation, is, once again, the special nerve endings which sense pressure.

Severe Diarrhea And Flushing

High levels of calcitonin caused by medullary thyroid carcinoma can lead to severe diarrhea and flushing similar to those seen in carcinoid patients due to high levels of calcitonin.4 However, this is usually very rare, and the mechanism is not well understood. It is thought that it could be related to disordered intestinal motility and/or increased secretion of salt and water, especially in the ileum, due to high levels of the prostaglandins E2 and F2-.5

What Causes Fatigue In People With Hypothyroidism

The general fatigue associated with hypothyroidism is caused by a number of different mechanisms but is primarily the result of an overall decrease in metabolism.

Cells throughout the entire body rely on thyroid hormone to perform their basic metabolic functions. A lack of thyroid hormone results in a slower basal metabolic rate. When metabolism is low, activity of the mitochondria within cells is impaired, which leads to low levels of ATP and, ultimately, to generalized fatigue. In addition to general fatigue, low ATP levels also contribute to muscle symptoms such as increased muscle tension, pain, and weakness.

Furthermore, patients with hypothyroidism are known to produce more lactic acid, which also contributes to muscle pain, muscle cramps, and fatigue.

Many individuals with hypothyroidism may notice fatigue especially with physical exertion. This is caused in part by the direct effects of thyroid hormone on heart tissue. Without enough thyroid hormone, the heart slows down and decreases the amount of blood pumped, reducing the flow of oxygenated blood to the tissues.

Because thyroid hormone also influences blood sugar metabolism and blood flow to the brain, thyroid hormone deficiency also can cause fatigue by decreasing the amount of glucose and oxygen available to the brain. This leads to the lethargy, forgetfulness, and depression common to those with hypothyroidism.
