An under active thyroid, also called hypothyroidism, may result in weight gain, fatigue, extreme cold, and increased menstrual periods in women. When the thyroid gland’s activity increases beyond normal, a condition called hyperthyroidism develops. Symptoms include pounding heartbeat, extreme anxiety, rapid weight loss and raised temperature.

While several factors may result in either condition, the most common causes are autoimmune diseases called Graves’s disease or autoimmune hyperthyroidism and Hashimoto’s thyroiditis or autoimmune hypothyroidism (AITDs).

An autoimmune disease is a disease in which the body’s immune system, which normally protects against invaders such as viruses and bacteria, becomes confused and attacks healthy tissue. In this case, the immune system attacks the thyroid gland, causing it to malfunction.

Vitamin D has been linked to various autoimmune disorders such as rheumatoid arthritis, inflammatory bowel disease, asthma and multiple sclerosis. Recent studies have also linked it to autoimmune thyroid diseases.

Recently, a study was undertaken to evaluate the levels of vitamin D in patients with AITDs compared to patients with non-AITDs and healthy controls. Serum vitamin D (25-OH) levels were measured in 50 patients with AITDs, 42 patients with non-AITDs and 98 healthy subjects. Vitamin D deficiency was designated at levels lower than 10 ng/ml.

Results showed that vitamin D deficiency was significantly higher in patients with AITDs compared with healthy individuals (72% versus 30.6%), as well as in patients with Hashimoto’s thyroiditis compared to patients with non-AITDs (79% versus 52%). Vitamin D deficiency also correlated to the presence of antithyroid antibodies and abnormal thyroid function tests.

The study suggests the involvement of vitamin D in the pathogenesis of AITDs and advises vitamin D supplementation.

Are you gaining weight? Your warm home in winter may be contributing to your weight gain. Can’t believe, see for yourself…

According to a recently published review paper, more time spent in thermal comfort may promote obesity, by turning down the body’s own thermostat and its ability to effectively burn fat. According to the authors, reduced exposure to seasonal cold may have a dual effect on energy expenditure, both minimizing the need for physiological thermogenesis and reducing thermogenic capacity.

The authors have also discussed about the role of brown adipose tissue in human heat production. Brown fat differs from white fat in that it has the capacity to burn energy to create heat, and its development in the body is thought to be triggered by exposure to cold temperatures.

The rise in the prevalence of obesity needs greater concern. Studies have also found association between low vitamin D levels and obesity. Vitamin D supplements have the potential to fight obesity. Want to learn more about vitamin D and its association with obesity? Click here.

If you have gone through the article “Lose weight with vitamin D”, you may know that obesity is directly associated with vitamin D deficiency. Obese persons are more likely to be vitamin D deficient. Another study adds to the evidence.

A latest research conducted at the Rikshospitalet-Radiumhospitalet Medical Center in Oslo, Norway suggests that obese people have lesser circulating levels of vitamin D in the blood. The study that was recently published in the Journal of Nutrition, evaluated the body composition of 1779 patients with excess body weight. They measured the serum levels of vitamin D and 1,25(OH)2D of these patients.

The study found that various factors like age season and gender also influenced the serum 1,25(OH)2D levels. They noted that generally people with higher BMI had lower levels of vitamin D.

Keep a check on your weight. Being overweight and vitamin D deficiency have been found to be closely associated. If you are overweight, and trying to lose weight, vitamin D supplementation may help.

Vitamin D deficiency is known to cause a number of health conditions like hypertension, coronary heart disease and diabetes in addition to weight gain. According to the data from a recent study at University of Michigan, vitamin D deficiency may be a significant  contributing factor for obesity in children. Let’s take a closer look…

The investigators recruited a group of 479 school children aged 5-12 years from Bogota, Colombia, in 2006 and followed them for about 30 months. They measured vitamin D in blood at the beginning of the study, and then examined the link between vitamin D levels and changes in three indicators of body fat over time: body mass index, waist circumference and sub scapular-to-triceps skin fold ratio.

They found that the kids with the lowest vitamin D levels at the beginning tended to gain weight faster than the kids with higher levels. Moreover, vitamin D deficiency was also linked to slower growth in height among girls but not boys.

The findings clearly suggest that low vitamin D levels may put children at risk of obesity. It is also significant because vitamin D insufficiency is highly prevalent across the globe and childhood obesity rates are dramatically increasing worldwide.

If you are concerned about weight gain, you should keep a watch on your vitamin D level and take vitamin D supplements.
