Vitamin D is extremely important for human health, but "everything over and above turns against it." Learn about the most important side effects that may result from excessive vitamin D in the body in this article.
Vitamin D is of great importance in the human body, but what happens if its levels rise? Find out this information now.
How does vitamin D work in the body?
It is a hormone. This hormone acts to absorb calcium from the food in the digestive tract to the body.
It is produced by the body as a result of exposure to sunlight, and can be obtained from certain foods such as certain types of fish and egg albumin.
Like any other hormone in the body, vitamin D works to build the body and plays many roles in keeping human body cells healthy and functioning the way they should work.
If vitamin D increases in the body, the increase may harm the body.
Some of the side effects that the body may experience if you get excessive amounts of vitamin D include:
1. rise in blood levels
When the body acquires adequate levels of vitamin D in the blood, it helps to increase immunity and protection from diseases such as osteoporosis and cancer.
Studies recommend that a vitamin level of 40-80 ng / ml (100-200 nmol / L) be maintained, and states that levels above 100 ng / ml (250 nmol / L) may be harmful.
Although there are many people taking vitamin D supplements, it is rare to find someone with very high blood levels of this vitamin.
A study of more than 20,000 people over a 10-year period found that only 37 people had levels above 100 ng / ml (250 nmol / L).
Only one person had a true percentage of toxins, at 364 ng / ml (899 nmol / L).
2. High blood calcium levels
Gastrointestinal disorders, such as vomiting, nausea and stomach pain.
Fatigue, dizziness and confusion.
Severe thirst
frequent urination.
The normal rate of calcium in the blood is 8.5-10.2 mg / dL (2.1-2.5 mmol / L).
Taking too much vitamin D can lead to high levels of calcium in your blood, which can cause many serious symptoms.
3. Nausea, vomiting and poor appetite
There is a close relationship between too much vitamin D intake and high blood calcium. This leads to nausea, vomiting and poor appetite.
However, these symptoms do not appear in everyone who has increased calcium in the blood.
In a study of 10 people who took vitamin D based on the appearance of deficiency in the body, after taking overdoses of vitamin D, 4 of them showed vomiting, nausea, and 3 on loss of appetite.
4. Stomach pain, constipation or diarrhea
Stomach pain, constipation and diarrhea occur if the digestive system does not tolerate food, or irritable bowel syndrome, a term used to describe colon discomfort.
However, they can also be a sign of high calcium levels caused by vitamin D.
These symptoms may occur in people receiving high doses of vitamin D to make up for the deficiency, as with other symptoms.
In one study of two boys, one suffered stomach pain and constipation after taking the incorrectly prescribed vitamin D supplements, while his brother experienced high blood levels without any other symptoms.
In another case study, an 18-month-old child was given 50,000 units of vitamin D for three months at which time he faced diarrhea, stomach pain and other symptoms.
These symptoms were overcome after the child stopped taking supplements.
5. Weak bone mass
Because vitamin D plays an important role in calcium absorption and bone metabolism, this helps maintain strong bones.
On the other hand, vitamin K2 functions are important in maintaining calcium in the bones and out of the blood. It is believed that very high levels of vitamin D may reduce vitamin K2 activity.
To protect yourself from bone disease, you should avoid taking too much vitamin D supplements and eating foods rich in vitamin K2, such as dairy and meat.
6. Renal failure
Excessive vitamin D intake leads to kidney injury.
In one case study, a man was hospitalized after kidney failure, a rise in blood calcium level and other symptoms that occurred after receiving a vitamin D injection prescribed by his doctor.
A study of 62 people who received high doses of vitamin D, each person suffered from kidney failure, whether they have a healthy kidney or existing kidney disease.
Renal failure is treated with oral or intravenous hydration and medications.
Summary: Vitamin D is very important for public health, so you should take it and get it at the required levels, not to increase it to reduce the risk of side effects mentioned in the article.
