Why Do We Need Vitamin D?

Your immune system, mental well-being, strong muscles, and strong bones and teeth are all supported by vitamin D. Vitamin D deficiency treatment Dubai focuses on restoring healthy levels to protect overall wellness. What occurs if you don’t receive enough of it, and how can you obtain it?

Vitamin D is not a vitamin; rather, it is a hormone that your body creates in reaction to sunshine. Although only around 10% of your vitamin D will be absorbed this way, you can also obtain it from food.

Different types of vitamin D exist. For instance, vitamin D2 is found in plant-based and fortified foods, whereas vitamin D3 is obtained from animal products and sun exposure.

In this article, we’ll explain why vitamin D is essential and what happens if you don’t get enough of the vitamin from sunshine. Check out our best advice on raising vitamin D levels if you’ve already had a Vitamin D test Dubai and want to elevate your levels.

Why do we need vitamin D?

Vitamin D is necessary for strong bones, muscles, and teeth. For those with significantly low levels, vitamin D replacement therapy Dubai offered by Dr. Barbara provides a structured treatment plan to restore optimal levels safely. A vitamin D deficiency can affect the health of your bones since it also keeps calcium from being lost through the kidneys.

A compromised immune system, depression, and some lifestyle-related illnesses, including diabetes, have also been connected to vitamin D deficiency. Consulting an endocrinologist for Vitamin D issues Dubai, Dr. Barbara can help manage hormonal balance and long-term health concerns.

How do we get vitamin D?

Vitamin D is also referred to as the sunshine vitamin since it is mostly obtained from sun exposure. If you spend most of your time indoors or covered up, or if there is little sunshine throughout the cooler months, this process becomes more challenging. Certain foods and supplements are your secondary source of vitamin D.

For strong bones and muscles, health authorities now recommend that adults and children over one year old consume 10 micrograms of vitamin D daily. Therefore, throughout the cooler months, the health authorities recommend that everyone take a daily vitamin D supplement. Consider consulting Dr. Barbara about vitamin D injection Dubai if you are at higher risk and supplements alone are insufficient.

The following individuals are more susceptible to vitamin D deficiency:

  • Infants
  • Women who are pregnant
  • The elderly
  • Dark-skinned individuals

What happens if I don’t get enough vitamin D?

Your body needs vitamin D to absorb calcium. You risk developing conditions where your bones become porous and brittle (osteopenia and osteoporosis) or weak and misshapen (osteomalacia in adults and rickets in children) if you don’t receive enough.

Due to its effects on the immune system, vitamin D deficiency can potentially raise the risk of infections.

Research has connected a lack of vitamin D to several illnesses, such as:

  • Breast cancer
  • Colon cancer
  • Heart conditions
  • Being overweight
  • Cancer of the prostate

Seven signs of a vitamin D deficiency

You might not be aware that you are deficient in vitamin D because its symptoms might be mild.

The following are seven typical indicators of a vitamin D deficiency:

  1. Brain fog
  2. Hair loss
  3. Irritability
  4. Pain in the bones and joints
  5. Depression
  6. Fatigue
  7. Weight Gain

Long-term, a vitamin D deficiency can affect:

  • Bone health: The body will only absorb 10–15% of calcium and 60% of phosphate from foods if vitamin D is not present. The parathyroid hormone (PTH), which maintains strong and healthy bones, is triggered by calcium phosphate. PTH will accelerate bone deterioration to release more calcium and phosphate if your body is deficient in vitamin D, which will lower your bone mineral density (BMD). An increased risk of fractures can result from osteopenia and osteoporosis. Weakness and bone deformities (adult osteomalacia and childhood rickets) can result from a significant deficiency of calcium and phosphate in the bones.
  • Immune system: Elevated autoimmunity and infection susceptibility are linked to low vitamin D levels. Vitamin D aids in the production of T cells during viral infections, such as the common cold. The T cells aid in the fight against the illness by eliminating the infected host cells. According to one study, Vitamin D supplements Dubai significantly strengthen the immune system.

Research is ongoing, but low vitamin D levels are associated with increased risk of many chronic diseases, including:

  • Autism in children
  • Heart-related conditions
  • Cancer
  • Depression
  • Diabetes
  • Complications during pregnancy
  • Severe asthma

The following conditions may benefit from vitamin D’s prevention and treatment:

  • Diabetes
  • Intolerance to glucose
  • Multiple sclerosis

How is vitamin D deficiency diagnosed?

A blood test to determine your blood levels of 25-hydroxy-cholecalciferol (25 (OH) D) is typically the first step in diagnosing vitamin D insufficiency. Since 25 (OH) D is the main form of vitamin D that circulates in the blood, testing for it is the most reliable method of determining how much vitamin D is present in your blood. However, if you have chronic kidney disease, your test findings might not be accurate (you should see your doctor for further information).

Nearly one billion individuals globally have inadequate levels of the sunlight vitamin, and one in five adults in the UAE has insufficient vitamin D levels.

Six causes of low vitamin D

1. Not spending enough time outdoors

Despite the UAE’s abundant sunshine, vitamin D deficiency remains common due to indoor lifestyles and cultural clothing choices. During the cooler months UAE residents may not receive sufficient UVB rays to produce adequate vitamin D.

Inadequate sun exposure is one of the leading causes of vitamin D insufficiency in the UAE. Most residents can obtain adequate vitamin D through brief sun exposure with their lower legs or forearms uncovered; this can all change in the cooler months.

2. Being over 65 or under six months old

Vitamin D insufficiency is more common in those over 65. Scientists believe that the body’s deteriorating capacity to absorb, synthesize, and transform vitamin D into its active form with age may be the reason for high levels of vitamin D insufficiency in this age group. A supplement or drops are advised for the first six months of nursing since human milk alone may not supply adequate vitamin D, putting breastfed infants under six months at risk for vitamin D insufficiency. Low Vitamin D treatment Dubai is often recommended for high-risk age groups.

3. Having a darker skin tone

Melanin, the pigment that gives your skin, hair, and eyes their color, is more abundant in persons with darker complexion, such as those of African, African-Caribbean, or South Asian ancestry. As a result, the skin’s capacity to produce vitamin D in response to sunshine is diminished. To generate the same quantity of vitamin D as those with lighter skin, persons with darker complexion may need to spend more time in the sun. However, spending more time in the sun isn’t necessarily the best course of action. By using the sun responsibly, up to 90% of melanoma skin cancer occurrences might be avoided.

4. Certain medical conditions

Damage to the small intestine’s lining can impair the small intestine’s capacity to absorb nutrients from food, including vitamin D, in people with Crohn’s disease and celiac disease. Low levels of vitamin D in the body are caused by kidney disease because the kidneys are less able to convert it into the active form that the body needs. Because the liver and kidneys collaborate to convert vitamin D, liver disease can also impact vitamin D production and absorption. Finally, the way the body uses vitamin D can be impacted by some medications (such as anti-epileptic medications and weight-loss medications like Orlistat).

5. Lifestyle factors

Your chance of developing a vitamin D deficiency might be raised by variables such as your weight, smoking status, and pregnancy. A vitamin D deficiency may be more likely to occur in obese people. Researchers believe adipose tissue may retain vitamin D, reducing its ability to move through the body’s bloodstream. According to research, smoking can lower the body’s vitamin D levels and have an impact on lung function. The DHA advises taking a daily vitamin D supplement to make sure you are obtaining the recommended daily dose of vitamin D because the risk of a deficiency increases during pregnancy.

6. A lack of vitamin D in your diet

Low vitamin D levels can be caused by a diet deficient in vitamin D-containing foods, such as red meat, oily fish, egg yolks, and fortified cereals. Food can help replenish your vitamin D levels, but it cannot be your only source of vitamin D.

What happens if I get too much vitamin D?

Vitamin D toxicity is often brought on by taking too many vitamin D supplements over an extended period of time, rather than by your food or exposure to the sun, although it is also possible to have too much vitamin D. Still, this is uncommon. The quantity of vitamin D generated by sun exposure is controlled by the body, and fortified foods often don’t have dangerously high levels of the vitamin.

The primary effect of vitamin D toxicity is hypercalcemia, or an accumulation of calcium in the blood, which can result in several symptoms. Additionally, bone discomfort and kidney issues like calcium stones may develop from vitamin D toxicity.

Hypercalcemia symptoms include:

  • Vomiting
  • Nausea
  • Bone weakness
  • Frequent urination

Reducing dietary calcium intake and halting vitamin D intake from food and supplements are two ways to treat vitamin D toxicity. You could occasionally additionally require medicine. Always check the label to make sure you aren’t taking too much vitamin D if you are taking supplements; 400–800 IU (10–20 mcg) per day is generally sufficient.

How can I make sure I get the right amount of vitamin D?

Vitamin D insufficiency is common in the UAE. Since there is less natural sunshine in the cooler months, you are more likely to become deficient during these seasons. Therefore, if you are vitamin D deficient, cooler months are an excellent time to check your levels and think about taking a supplement.

Vitamin D blood testing in the UAE

A Vitamin D blood test Dubai is essential for detecting deficiency and preventing complications such as fatigue, bone weakness, and low immunity.
