Vitamin D Deficiency : Symptoms and Treatment, A Report

Vitamin D deficiency is quite widespread. Vitamins are classified as necessary nutrients because human body cannot produce them or produce insufficient amounts to prevent undesirable health effects or disorders. As a result, it’s crucial that people replenish their body with vitamins through diet and/or supplements.

The “sunshine” vitamin is a hot topic

Vitamin D, unlike other vitamins, acts as a hormone. It has receptors in many cells throughout your body. When your skin is exposed to sunlight, your body produces it from cholesterol. Vitamin D is an essential nutrient that serves a variety of functions throughout the body.

Vitamin D Deficiency

How Do People Get Vitamin D?

Vitamin D is obtained in three ways:

  • Through the skin
  • Through the diet
  • Through supplementation.

After being exposed to sunlight, Human body produces vitamin D on its own. However, because too much sun exposure can cause skin ageing and cancer, many people seek vitamin D from alternative sources.

Why do people need vitamin D?

Vitamin D aids calcium homeostasis and bone metabolism in the body. One of the most important components of bone is calcium.

It helps the body maintain normal bone formation and maintenance by enhancing calcium, magnesium, and phosphate absorption.

To maintain a healthy level of vitamin D, a circulating level of 25-hydroxyvitamin D greater than 30 ng/mL is required. Vitamin D insufficiency can cause a variety of issues, the most common of which being rickets in children and osteoporosis in adults.

Vitamin D is also important for the neurological, muscular, and immunological systems.It’s insufficiency is now linked to cancer, cardiovascular disease, diabetes, autoimmune illnesses, and depression, according to several conflicting studies.

How much vitamin D do humans need?

Human’s daily vitamin D need is determined on the basis of their age. The recommended amounts, in international units (IU), are

Birth to 12 months400 IU
Children 1-13 years600 IU
Teens 14-18 years600 IU
Adults 19-70 years600 IU
Adults 71 years and older 800 IU
Pregnant and breastfeeding women600 IU

People who are at a greater risk of vitamin D insufficiency may require more vitamin D. Consult with doctor to determine how much  require.

What causes vitamin D deficiency?

Vitamin D deficiency can occur for a variety of reasons:

  • Decreased dietary intake
  • Decreased absorption
  • Decreased sun exposure
  • Decreased endogenous synthesis
  • Increased hepatic catabolism
  • End organ resistance

Who is at risk of vitamin D deficiency?

Some persons are more susceptible to vitamin D insufficiency than others:

  • Breastfed infants
  • Older adults
  • Dark skinned people
  • Obese persons
  • People with absorption disorders (like Crohn’s disease or celiac disease)
  • Individuals who have undergone gastric bypass surgery
  • Those who suffer from chronic renal or liver illness
  • People with granulomatous diseases such as sarcoidosis, TB, histoplasmosis, or histoplasmosis
  • Sufferers who have lymphomas
  • Patients on medications which impair vitamin D metabolism (such as cholestyramine, anti-seizure drugs, glucocorticoids, antifungal drugs, and HIV/AIDS medicines)
  • Osteoporosis patients
  • People with hyperparathyroidism

If People think they could be deficient in vitamin D, go to the doctor. A blood test can be used to determine how much vitamin D is present in the body.

How can people get more vitamin D?

There are a certain foods that contain vitamin D naturally:

  • Fatty fish such as salmon, tuna, and mackerel
  • Cheese
  • Mushrooms
  • Egg yolks

Vitamin D is also found in fortified foods. Individual can find out if a food contains vitamin D by looking at the label. Vitamin D is frequently added to various foods (through biofortification) which include:

  • Cereals for breakfast
  • Orange juice
  • Yogurt and other dairy items
  • Drinks made from soy

Many multivitamins contain vitamin D. Vitamin D supplements are now available in pill and liquid form for newborns.

The treatment for vitamin D deficiency is to take supplements. Consult with doctor about how much one should take, how often one should take it, and how long one should take it.

What problems does vitamin D deficiency cause?

Vitamin D insufficiency can cause bone density loss, which can lead to osteoporosis and fractures.

Vitamin D deficiency can also lead to the development of other disorders. It can cause rickets in youngsters. Rickets is an uncommon condition that causes softening and bending of the bones.

Rheumatoid arthritis is more common in African American infants and children. Severe vitamin D deficiency in adults causes Osteomalacia. Osteomalacia is characterized by brittle bones, discomfort in the bones, and muscle weakness.

Vitamin D is being studied for its potential links to a variety of medical disorders, including diabetes, high blood pressure, cancer, and autoimmune diseases like multiple sclerosis.


The severity of vitamin D deficiency is divided into mild, moderate, and severe:

Mild deficiencyless than 20 ng/mL
Moderate deficiencyless than 10 ng/mL
Severe deficiencyless than 5 ng/mL


Some of the signs and symptoms of vitamin D insufficiency are listed below:

Getting infected frequently

One of vitamin D’s most critical functions is to maintain your immune system healthy so you can fight off viruses and bacteria that cause sickness.It essentially deals with the cells that are in charge of battling infection.

Low vitamin D levels may be a contributing cause if you become sick frequently, especially with colds or the flu.

A relationship between a deficit and respiratory tract illnesses such colds, bronchitis, and pneumonia has been discovered in many extensive epidemiological studies.

Taking vitamin D supplements at a dose of up to 4,000 IU per day has been shown in several studies to lessen the chance of having a respiratory tract infection.

Bone and back pain

Vitamin D is beneficial to bone health in a variety of ways.

It helps your body absorb calcium.  Inadequate vitamin D levels in the blood can cause bone pain and lower back discomfort.

A link between a deficit and chronic lower back pain has been discovered in large randomized trials.

Increased pain severity was linked to reduced vitamin D levels in one survey investigating 98 persons with lower back pain.

Vitamin D Deficiency

Another study of 81 papers discovered that patients with arthritis, muscle pain, and chronic generalised pain had lower vitamin D levels than those who did not have these illnesses.


A depressed mood could also indicate a vitamin D deficiency.

In one review, 65 percent of observational studies indicated a link between low vitamin D levels in the blood and depression. Researchers also noted that some of the trials may not have lasted long enough to evaluate the effects of vitamin D supplementation on mood.

Vitamin D supplementation has been proven in certain trials to help patients who are low in the vitamin improve their depression, especially seasonal depression, which occurs during the colder months.

Impaired Wound Healing

Poor wound recovery after surgery or injury could indicate a deficiency in vitamin D.

Vitamin D insufficiency hampered several elements of healing in persons who had oral surgery, according to a study of few researches.

Vitamin D’s involvement in reducing inflammation and fighting infection has also been considered to be vital for healthy healing.

Patients with diabetes-related foot infections were studied in a trial. It was shown that people with severe vitamin D deficiency had greater levels of inflammatory markers, which can impede healing.

Fatigue and Tiredness

Excessive tiredness and fatigue could indicate a vitamin D deficit. Taking vitamins can help you feel more energised.

Tiredness can be caused by a variety of factors, including vitamin D insufficiency.  The effects of vitamin D on exhaustion and sleep quality have also been studied in children. Low vitamin D levels were linked to lower sleep quality, reduced sleep duration, and later bedtimes in a study of 39 children.

Interestingly, some studies have discovered that supplementing with vitamin D might help patients with a shortage feel less tired.


Supplementation is the most common treatment for vitamin D insufficiency. If the doctor decides that people are deficient in this nutrient, the following options may be suggested.


Vitamin D supplementation can be used to address vitamin D insufficiency. These are widely available over the counter; however people should consult their doctor for exact dosage recommendations.

If anyone have a severe deficiency or if over-the-counter pills don’t help, the doctor may prescribe prescription vitamin D. These are available in significantly higher doses, up to 50,000 IU.

Vitamin D injections are another option the doctor may examine.

Natural treatments

Aside from vitamin D supplements, the doctor may advise people to increase the amount of vitamin D-rich foods in their diet. Among the possibilities are:

Egg yolks, fatty fish, biofortified food (such as milk, juices, and cereals), yoghurt, beef liver

Because sunlight is a natural source of vitamin D, the doctor may advise you to spend more time outside. However, because of the dangers of too much ultraviolet (UV) radiation, one must carefully follow the doctor’s advice.

Can too much vitamin D be harmful?

Quite so much vitamin D, sometimes known as vitamin D overdose, can indeed be dangerous. Sickness, vomit, a decreased appetite, diarrhoea, lethargy, and losing weight are all symptoms of poisoning.

Vitamin D overdose could potentially harm the kidneys. Vitamin D deficiency significantly boosts blood calcium levels. Hypercalcemia (excess calcium in the blood) could induce dizziness, confusion, and cardiac rate abnormalities.

The over use of vitamin D supplements is by far the most common cause of vitamin D overdose. So because system restricts the quantity of vitamin D it makes, prolonged sun exposure somehow doesn’t induce vitamin D intoxication.


Vitamin D insufficiency is quite widespread, yet the majority of the population is ignorant of it.

Because of indications are typically vague and generic, it’s difficult to determine if they’re triggered by low vitamin D levels or something else. It’s critical to chat with the doctor and have the blood levels checked if users suspect they have a deficiency.

A vitamin D shortage, however, is usually simple to correct.
