Vitamin D is among the vitamins necessary for both adult and child health. In vitamin D deficiency, various health problems can occur in both adults and children. For this reason, it is very important that the vitamin levels are at the desired level.
What is Vitamin D?
In medical language, calciferol is one of the types of fat-soluble vitamins that are stored in the liver and adipose tissue. It is divided into two types as D2 and D3. Vitamin D, which is taken from the sun and food, is transformed into a more effective chemical by undergoing changes in the liver and kidney.
What are the symptoms of vitamin D deficiency?
Vitamin D deficiency affects all systems of the body and invites many diseases. Today’s living conditions, working indoors, not performing outdoor activities adequately, malnutrition increase vitamin D deficiency. Vitamin D deficiency is a factor that affects all age groups and causes important health problems.
Vitamin D deficiency can occur with various symptoms. The important detail here is that people watch themselves and take the necessary precautions. Vitamin D deficiency symptoms can be listed as follows:
- General body pain
- Tiredness
- Difficulty walking (balance problem)
- Bone pain
- Loss of strength
- Hair loss
- Headache
- Depression
- Changeable mood
- Insomnia
- Pain in joints and fingers
- Under eye bruises
- Excessive sweating
- Difficulty losing weight
- Constant feeling cold
What are the causes of vitamin D deficiency?
Vitamin D deficiency can occur in the following situations:
- Not consuming products rich in vitamin D
- Inability to metabolize vitamin D
- Reduced vitamin D excretion
- Genetic diseases
- Not spending enough time in ultraviolet B (UVB) sunlight
What happens if you don’t get enough vitamin D
Insufficient sunbathing and a small amount of vitamin D in natural foods are common causes of vitamin D deficiency. In response to the question ‘What happens if you don’t get enough vitamin D?’, the following can be listed;
- A bone disease called osteomalasia seen in adulthood can be seen.
- When vitamin D deficiency leads to bone diseases, muscle and bone pain may be experienced, and they may be more likely to break or break a bone.
- Not getting enough vitamin D in babies and children can lead to rickets that cause growth retardation, muscle weakness and skeletal deformities.
- Bone metabolism cannot improve.
- Vitamin D helps your immune system function well. As a matter of fact, the fight against diseases may be insufficient in vitamin D deficiency.
- It prepares the ground for obesity.
- Sleep disturbances may occur.
- It can prepare the ground for Alzheimer’s disease.
- It can lead to chronic fatigue at any time of the day.
What diseases does vitamin D deficiency cause?
In people with vitamin D deficiency; It can cause health problems such as cancer, chronic fatigue, diabetes, hypertension, depression, rheumatism and heart diseases. Vitamin D deficiency; It also negatively affects bone density and invites bone diseases.
Bone loss (psteoporosis) and bone diseases
Bones have a lively structure just like other tissues, and long-term vitamin D deficiency can cause deterioration in bone structure, bone loss and muscle weakness. Depending on vitamin D, rickets in children, bone softening in adults, and osteoporosis can occur in later ages. Rickets refers to the softening and weakening of the bones due to vitamin D deficiency. This disease may cause permanent defects in the bone structure such as curvature of the legs, thickening of the hands and ankles, growth retardation, and breast bone deformity.
In vitamin D deficiency, bone pain can be seen with bone loss and this can be felt throughout the body. Later, weakness may accompany these pains. Foods containing omega-3, calcium, magnesium, potassium and vitamin D should be consumed to strengthen bones. In order to prevent osteoporosis that manifests itself in later ages, it is necessary to eat a healthy diet and maintain the vitamin D level together with other vitamins. Breast milk consumption in infancy is of great importance in order to avoid bone problems in later years.
Diabetes and heart disease
Problems such as diabetes, stroke, heart-related death risk, high blood pressure are also among the health problems that can be caused by vitamin D deficiency.
Cancer
Vitamin D deficiency can trigger cancer formation. Breast cancer in particular is thought to be linked to vitamin D deficiency. Women who have breast cancer and have a high vitamin D value have a longer life expectancy than those with a lower value. Increasing the vitamin D level of people with breast cancer to 50 ng / ml and above affects the treatment positively.
Since vitamin D increases communication between cells, it prevents them from dividing rapidly. By preventing the abnormal proliferation of cells, it accelerates the blood flow and slows the feeding of cancer cells. Since the harmful cells cannot be fed, they disappear after a while.
The vitamin D levels of women living indoors are around 17 ng / ml. In women without cancer, the vitamin D level should be at least around 30 ng / ml. When the vitamin D level rises to 50 ng / ml and above, the risk of developing breast cancer decreases by 50%.
According to researches, vitamin D deficiency also increases the risk of lung, colon and prostate cancer besides breast cancer.
What are the harms of vitamin D deficiency during pregnancy?
Vitamin D deficiency also manifests itself in gynecological diseases and birth. Vitamin D use is extremely important for maternal and child health during pregnancy. Since the baby in the womb meets the need for calcium from the mother, the vitamin D level must be sufficient to maintain the calcium balance of the mother during pregnancy and breastfeeding. The bones of babies of mothers with vitamin D deficiency may soften and weaken. Weakness of the baby’s muscles, closing or not closing the fontanel, weakness in teething are also associated with vitamin D deficiency. Deficient vitamin D intake during pregnancy can cause permanent damage in newborn babies and cannot be completely corrected with vitamin supplements after birth.
In vitamin D deficiency, there may be an increase in the risk of pre-eclampsia, which is called pregnancy poisoning, in expectant mothers. Fatigue, insufficient weight gain, fatigue, muscle and bone pain during pregnancy are also related to vitamin D. In addition, gestational diabetes and bone resorption are among the conditions that can occur in vitamin D deficiency. Cesarean delivery is more common in mothers with low vitamin D levels. Vitamin D supplementation should be started from the 12th week for expectant mothers and continued until the 6th month of the breastfeeding period.
People at risk of diseases seen in vitamin D deficiency
- Light skinned people
- The elderly people
- Diabetes patients
- Those who work indoors and wear closed
- Those who use high factor sunscreen
- Those with kidney and liver diseases
- Those with malnutrition
- Those who have stomach surgery
- During pregnancy and breastfeeding
- People using epilepsy medication
- Cortisone users
- Those with celiac disease
What is the optimal level of vitamin D?
- Extremely Low Vitamin D Level: below 30 nmol / L (12 ng / mL)
- Slightly Low Vitamin D Level: Between 30 nmol / L (12 ng / mL) and 50 nmol / L (20 ng / mL)
- Normal Vitamin D Level: Between 50 nmol / L (20 ng / mL) and 125 nmol / L (50 ng / mL)
- High Vitamin D Level: higher than 125 nmol / L (50 ng / mL)
Recommended daily vitamin D intake
The need for vitamin D varies according to age and person. While 400 IU is sufficient for babies up to 1 year old, 600 IU should be taken after 1 year of age. After the age of 70, the daily need for vitamin D increases. Low vitamin D levels can lead to a range of problems, particularly those related to bones and muscles.
What are the benefits of vitamin D?
Protects muscles and bones
Vitamin D is the vitamin that balances the blood levels of phosphorus and calcium substances. It is extremely important for dental and bone health. While it ensures the absorption of calcium in the intestines, it also reduces calcium loss in the kidneys. The hardening of bones with calcium accumulation occurs with vitamin D. Since it increases muscle strength and muscle mass, it decreases falls, especially in the elderly. It prevents the secretion of parathyroid hormone that causes bone resorption. For muscle and bone health, it is extremely important to pay attention to vitamin intake and diet.
Protects against diabetes
Vitamin D has the ability to protect against diabetes. It is seen that Type 1 diabetes decreases in children who have enough vitamin D, and Type 2 diabetes increases in those with low levels. In addition, conditions such as metabolic syndrome occur in people with vitamin D deficiency.
Protects the immune system
Vitamin D is among the vitamins that strengthen the immune system. Providing protection against diseases by strengthening immunity, vitamin D is beneficial for all cells in the body. Low vitamin D is found in diseases caused by the immune system such as ulcerative colitis, Crohn’s, Multiple Sclerosis (MS). It is seen that these diseases can be prevented with sufficient vitamin D.
Protects heart health
Vitamin D is good for heart health and its diseases. It has a protective effect against diseases related to high blood pressure, heart diseases and some types of cancer.
Vitamin D sources
The most important source of vitamin D that the body needs is sunlight. In other words, the sun, which causes many skin diseases, has health benefits as well as health benefits. The ultraviolet rays in the sun provide 95% of the vitamin D required for the body, and the rest is provided by food. For this, the skin must be exposed to direct sunlight. Sun exposure over clothes or behind windows is not effective in eliminating vitamin D deficiency. Likewise, sunscreens of a factor of 20 or more used while sunbathing also prevent the production of vitamin D in the skin. Since indoor environments cause vitamin D deficiency, it is more important to go outdoors. The reason why vitamin D deficiency is seen at almost every age is the inability to benefit from the sun sufficiently. Since prolonged exposure to the midday sun may have negative effects, especially on hot summer days, it will be good to go out in the morning and afternoon hours. Sunlight requirements may vary depending on the skin color, age and sunbathing style of the person. People with dark skin need sunlight for a longer time, especially in winter, in order for sufficient vitamin D to form on the skin.
Vitamin D foods
In order not to experience vitamin D deficiency in months or regions where the sun is scarce, it is necessary to add foods containing vitamin D to the diet. The following foods can be listed as an answer to the question of what vitamin D contains:
- Fish varieties rich in fat (salmon, mackerel, tuna, sardines)
- Milk and milk products
- Egg
- Natural juices such as orange juice
- Chicken livers
- Fish oil
- Grain products
- Clover
- Dead nettle
- Parsley
Vitamin D Supplements
Before taking vitamin D supplements (vitamin D drugs), a doctor should be consulted and an appropriate vitamin D deficiency treatment should be performed. You can make an online hospital appointment to find out about vitamin D deficiency. The diagnosis of vitamin D deficiency is made by measuring the vitamin D level in the blood. Oral treatment is recommended for those who cannot meet the daily needs. Higher doses of vitamin D supplements can be administered by injection from the hip. According to researches, the absorption of the vitamin is higher when vitamin D pill or vitamin D drops are taken with fatty meals.
What are the harms of high vitamin D levels?
Too much of everything is harmful to the body. The same is true for the amount of vitamin D, and too much can lead to poisoning.
The high level range for vitamin D stored in fat and not excreted in urine is 125 nmol / l or more. High vitamin D levels can lead to calcium deposits in organs and soft tissues. The haphazard use of vitamin D can result in high blood levels. The damages of using too much vitamin D can be listed as follows.
- Tissue and joint calcifications
- It can lead to kidney stone formation and kidney damage.
- It can lead to hypertension
- It can cause an increase in calcium in the blood.
On the other hand, excess vitamin D can lead to poisoning, and kidney failure and heart failure that develop as a result of this poisoning can lead to death. Early toxicity (intoxication) symptoms can be seen as bone pain, dizziness, dry mouth, constipation, persistent headache, thirst, myalgia, anorexia, nausea, vomiting, and irregular heartbeat. Symptoms of chronic toxicity may manifest themselves with skin itching, nausea, sexual reluctance, severe stomach pain, psychiatric problems, bone pain, cloudiness in urine, eyes sensitive to light, vomiting.
Note: Vitamin D poisoning does not occur with sunbathing as the sun rays remove the excess vitamin D.
