Besides vitamin D deficiency
can cause some diseases, we are also should know that vitamin D
toxicity also caused several health problems. Vitamin D is beneficial to
health, such as preventing diabetes, bone disorders or muscle
disturbances. However, excessive intake of vitamin D, it also can lead
to health problems. It is based on a study from John Hopkins University
shows that consume excess vitamin D will not gives any benefit to the
body, in fact, can cause problems. The study published in the American
Journal Of Medicine, which recommends that vitamin D should not be
excessive, because it can increase the risk of cardiovascular disorders.
Can we overdose on vitamin D?
Consuming vitamin D as much as 10 times the recommended daily dose, for
several months, can cause poisoning, which resulted in high levels of
calcium in the blood. The first symptoms of vitamin D toxicity are loss
of appetite, nausea and vomiting, followed by an incredible thirst,
increased urination, weakness, anxiety and high blood pressure. Calcium
can be deposited throughout the body, especially in the kidneys, which
can cause permanent damage. Renal function is impaired, causing protein
in the urine discarded and urea levels in the blood increase.
Vitamin D Overdose Symptoms
Symptoms of vitamin D overdose can vary from mild to serious. Some of
these symptoms for example nervousness, irritability, and emotional.
While the physical signs that can arise include nausea, vomiting, loss
of appetite, and weight loss. In addition, increased thirst and
dehydration, as well as severe headaches can occur. Along with the
development of symptoms, nerves and muscles begin to be affected, which
causes itching in the skin, fatigue, and weakness.
A more serious concern due to the toxicity of vitamin D in the body are
elevated levels of calcium in the blood and soft tissues (such as the
lungs, heart, and kidney). At this point, bone pain or bone loss can
occur. Symptoms can also affect the urinary tract, ranging from
excessive urine production by the kidney stones, and even kidney
failure. High blood pressure and increased risk of heart disease to be
one of the feared condition occurs.
Diagnosis of Vitamin D Overdose
An overdose of vitamin D are rare and only showed slight specific
symptoms, making diagnosis difficult. If you are worried about
experiencing vitamin D toxicity, consult with a physician or other
health care related to examine and recommend treatment if necessary.
Excess Vitamin D Increase Risk of Death
The researchers cautioned that, excess vitamin D levels in the blood
increase the risk of death. Too much and too little vitamin D had the
same result against body. A study conducted by researchers at the
University of Copenhagen, Denmark, found the mortality rate increases to
40% in people with vitamin D in the blood is very high. This study is
based on tests of blood samples from 247 574 patients from Copenhagen
General Practitioners Laboratory, as reported by Dailymail.
The results showed, when the blood contains less than 10 nanomoles
(nmol) of vitamin D per liter of serum, the risk of death doubled to
2.31 times higher than average. However, if the blood contains more than
140 nmol of vitamin D per liter of serum, the risk of death rose 1.42
times, or approximately 40% higher. While the lowest mortality rate if
blood containing 50 nmol of vitamin D, according to a report in the
Journal of Clinical Endocrinology and Metabolism.
Vitamin D is essential for the immune system, healthy bones and strong
teeth, as well as the absorption of calcium. If a lack of vitamin D, you
could be at risk for heart disease, type 2 diabetes, some types of
cancer, autoimmune, and osteomalacia. Darshana Durup researchers from
the Faculty of Health and Medical Sciences at the University of
Copenhagen said, many studies have been conducted to determine the risk
of vitamin D deficiency, however, proved too much vitamin D is also not
good. So, if you want to take supplements of vitamin D to meet the daily
needs, it is advisable to consult a doctor.
