How Does Low Vitamin D Affect Vein Health?


Do you know what happens if you have low Vitamin D in your body? Vitamin D deficiency leads to a loss of bone density and can therefore cause a host of other health problems. Let’s take a closer look at the reasons for low Vitamin D levels and the symptoms of Vitamin D insufficiency. We will also talk about the different ways in which we can get more vitamin D and the advantages of having adequate levels of this vitamin. 

What Is Vitamin D?

Vitamin D is essential for maintaining healthy bones and teeth. The human body produces Vitamin D through sun exposure. There are two types of Vitamin D, mainly D2 and D3. 

What Are the Sources Of Vitamin D?

Vitamin D Source

The easiest way to boost the body’s vitamin D production is to expose it to adequate sunshine. Vitamin D may also be found in a variety of foods, including:

  • Cereals
  • Milk
  • Egg yolk
  • Cheese
  • Paneer
  • Fatty fish like salmon, tuna, mackerel

What Are The Signs And Symptoms Of Low Vitamin D?

 The signs and symptoms of Vitamin D deficiency are:

  • Muscle pain, muscle weakness, muscle cramps
  • Fatigue
  • Back pain
  • Increased chances of contracting infections 
  • Falling sick quite often
  • Mood swings
  • Hair loss

 What Are The Causes Of Low Levels of Vitamin D?

Vitamin D deficiency can be caused by the following reasons:

  • Obesity: People with a higher Body Mass Index (BMI) need higher vitamin D doses to achieve and maintain adequate levels.  
  • Specific medical conditions like cystic fibrosis, Crohn’s disease, and Celiac Disease: These diseases do not allow the body to absorb vitamin D efficiently.
  • Weight loss surgeries: Surgeries such as bariatric surgery can increase the risk of vitamin D deficiency as they can limit the absorption of nutrients.
  • Kidney And Liver diseases: These diseases reduce the amount of an enzyme required to convert vitamin D into a form that the body can use. Inadequate levels of active vitamin D in the body can result from a lack of this enzyme.

How Is Low Vitamin D Diagnosed? 

If you experience symptoms of vitamin D insufficiency, your doctor will recommend a blood test to check vitamin D levels. Similar to any other blood test, a technician will draw blood from the vein with a needle. You do not need fast or do any other preparation for such a blood test.

How Can You Prevent Vitamin D Deficiency?

To maintain adequate levels of Vitamin D, consult your doctor with your blood reports. If required, your doctor will prescribe a Vitamin D supplement. However, along with the supplements, you may also need to make some other changes in your lifestyle.

  • Eating foods containing Vitamin D: Consciously include more vitamin D-rich foods in your diet. However, keep in mind that food alone cannot meet the daily requirement of vitamin D.
  • Exposure To Sunlight: To absorb enough vitamin D, 15 to 30 minutes of sun exposure to the face, arms, legs, or back, two to three times a week could be sufficient.

What Are The Advantages Of Having Sufficient Vitamin D In The Body?

Vitamin D serves various functions in the body. Some of these are:

Healthy Bones

Vitamin D is important in the management of calcium and the preservation of phosphorus levels in the blood. These aspects are crucial for sustaining bone health.

Vitamin D is also required by the intestines to activate and absorb calcium and recover calcium that the kidneys would otherwise excrete.

Healthy Infants And Children

Vitamin D promotes calcium absorption, which is then used in the formation and strengthening of bones. Children and babies are more susceptible to fractures and growth difficulties if they lack Vitamin D. Therefore, breastfeeding infants are given Vitamin D drops to develop the brain and immune system.

Healthy Pregnancy

Vitamin D supports the growth of the unborn child as well as the pregnant woman’s immunity. This is why most doctors prescribe a supplement to expecting mothers to increase the level of vitamin D in the body.

Can You Have Too Much Of Vitamin D?

Surprisingly, there is no such thing as too much vitamin D from the sun. While Vitamin D poisoning is possible, it is quite uncommon.

Vitamin D poisoning can cause hypercalcemia, with symptoms including:

  • Nausea
  • Diarrhea
  • Loss of Appetite
  • Constipation
  • Confusion
  • Weakness

Do not take higher-than-recommended vitamin D dosage without consulting your doctor first.

What Happens To Your Vein Health When You Have Low Vitamin D?

Your blood vessels will most likely suffer if you don’t have enough vitamin D in your body. Vitamin D promotes normal blood flow by keeping your blood vessels flexible and relaxed. As a result, if your vitamin D levels are low, your veins may struggle to function correctly, and vein problems may develop.


If you are low on Vitamin D and are experiencing any of the symptoms listed above, we suggest that you have your blood work done and examined by your doctor. He may prescribe a vitamin D supplement. Moreover, it is recommended to have a diverse diet rather than focusing on a single nutrient as the key to optimal health.
