Hyperthyroidism update: Breast cancer, hypothyroidism vs hyperthyroidism, atrial fibrillation, atherosclerosis

Hyperthyroidism increases risk of breast cancerThe thyroid is a gland found in the neck that is responsible for secreting thyroid hormone, which primarily influences metabolic rate and protein synthesis. An estimated 20 million Americans have some sort of thyroid disease, with 60 percent of those individuals unaware of their condition. We at Bel Marra feel that we should inform our readers about this condition by providing you articles on the subject. We have relevant information on how hyperthyroidism (increasing thyroid hormone) is linked to an increased risk of breast cancer as well as how hyperthyroidism is linked to atrial fibrillation and atherosclerosis. To better round off your knowledge on abnormalities of the thyroid gland, we have also included an article on hypothyroidism vs hyperthyroidism.

Hyperthyroidism increases risk of breast cancer

A link has been found between overactive thyroid and breast cancer whereby women who have hyperthyroidism have been found to have an increased risk of breast cancer. According to researchers, the risk is 11 percent higher, compared to women with normal functioning thyroids.


Although hyperthyroidism was associated with an increased risk of breast cancer, hypothyroidism – an underactive thyroid – was found to decrease the risk of breast cancer by six percent.

The findings come from a 36-year review that identified nearly 80,000 Danish women with hyperthyroidism and over 61,000 women with hypothyroidism. All the women were cancer free at the beginning of the study. Continue reading…

Hypothyroidism vs. hyperthyroidismHypothyroidism vs. hyperthyroidism symptoms, living with thyroid diseases

Hypothyroidism and hyperthyroidism are two common forms of thyroid diseases, which – if left unmanaged – can make daily living quite challenging. Hypothyroidism is also known as an underactive thyroid, meaning the thyroid doesn’t produce enough hormones, thus slowing down bodily functions. In hyperthyroidism – overactive thyroid – the thyroid overproduces thyroid hormones, which in turn speed up bodily functions.

Hypothyroidism is a long-term health problem that needs to be managed throughout a person’s life. In hyperthyroidism, some cases may be temporary if they are a result of pregnancy or an autoimmune disease known as Grave’s disease, which does not have a cure. Continue reading…

Atrial fibrillation risk increases in people with hyperthyroidismAtrial fibrillation risk increases in people with hyperthyroidism compared to those with normal thyroid function

Atrial fibrillation (irregular heart rhythm) risk is higher in people with hyperthyroidism, compared to individuals with normal thyroid function. Hyperthyroidism is a condition where the thyroid is overactive and produces too many hormones. The findings suggest that doctors should monitor heart rhythms in hyperthyroidism patients.

The connection between overt hyperthyroidism and atrial fibrillation is well known, but there isn’t much evidence on whether milder hyperthyroidism is associated with an irregular heartbeat. Furthermore, irregular heartbeat and hypothyroidism also has very limited data available.

A Denmark-based research team aimed to examine any possible link between atrial fibrillation in a wide spectrum of thyroid disorders. Continue reading…

Healing thyroid disorders hypothyroidism and hyperthyroidism naturallyHealing thyroid disorders hypothyroidism and hyperthyroidism naturally

The thyroid gland is prone to two main disorders: hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). In hypothyroidism, the thyroid does not produce enough hormones causing many bodily functions to perform slower. In hyperthyroidism, too many hormones are being produced causing bodily systems to overwork.


To better understand the detrimental effects of either condition, it’s important to understand the importance of the thyroid and what it is really. Continue reading…

Increased thyroid hormone levels may be tied to atherosclerosisIncreased thyroid hormone levels may be tied to atherosclerosis

The thyroid is an important gland in our body that helps regulate many bodily processes, from our metabolism to protein synthesis. However, according to a new study, middle-aged individuals, as well as the elderly with elevated levels of thyroid hormone, may be at risk for developing hardened blood vessels (atherosclerosis) due to plaque buildup, subsequently increasing their risk for heart disease and stroke.

Atherosclerosis is a disease where plaque builds up inside the arteries: the vessel that carries oxygen-rich blood to your heart and other organs. Plaques are usually made up of fat, cholesterol, calcium, and other substances found in the blood, and over time, its accumulation can lead to blood vessel hardening and narrowing. This is a big problem, as it limits the flow of oxygen-rich blood throughout the body, leading to heart attacks, strokes, and even sudden death. Continue reading…
