Medical conditions that can cause
Today, 25(OH)D less than 12 ng/mL is considered evidence of severe vitamin D deficiency.
Vitamin D deficiency can cause a number of neurological problems, including fatigue, memory loss, and difficulty concentrating. This means having a vitamin D deficiency treated with a supplement can possibly help improve your concentration levels.
Recent studies have confirmed an association between cognitive impairment, dementia, and vitamin D deficiency.
Research has shown that maintaining enough vitamin D in the body may lower the risk of multiple sclerosis (MS). Several studies have shown that people who get more sun exposure and vitamin D in their diets are less likely to have MS .
Levels of 12 ng/ml are too low and levels of 50 ng/ml are too high. High or low levels may affect a person's health. However, needs vary between individuals. The body depends on vitamin D for a variety of reasons, but it is especially important for bone health.
Having inadequate levels of vitamin D may correlate with unintentional weight gain. A study on women over the age of 65 found that participants with a lower vitamin D level experienced more weight gain. A systematic review of 23 different studies found similar associations between vitamin D deficiency and obesity.
Levels of 50 nmol/L (20 ng/mL) or above are adequate for most people for bone and overall health. Levels below 30 nmol/L (12 ng/mL) are too low and might weaken your bones and affect your health. Levels above 125 nmol/L (50 ng/mL) are too high and might cause health problems.
Certain chronic conditions
Cystic fibrosis, Crohn's disease, and celiac disease, for example, can reduce the ability of the intestines to absorb enough vitamin D into the bloodstream—leading to low circulating levels of vitamin D, which means there's less of it for different parts of your body to use.
Vitamin and mineral deficiencies
Other vitamin deficiencies linked with muscle weakness include: calcium deficiency (hypocalcemia) potassium deficiency (hypokalemia) iron deficiency (anemia)
In general, the two main causes of vitamin D deficiency are: Not getting enough vitamin D in your diet and/or through sunlight. Your body isn't properly absorbing or using vitamin D.
Besides boosting mood and promoting calcium absorption, recent studies have shown that vitamin D may also aid in weight loss. For people with extra belly fat, a vitamin D supplement may be beneficial.
Recent findings: Low vitamin D levels are associated with increased symptoms of depression and anxiety. For this reason, vitamin D screening should be performed in the prevention and treatment planning of these mood disorders.
Dizziness is a common symptom of vitamin D deficiency, along with fatigue and brain fog. If you are feeling dizzy all the time, it is worth checking your vitamin D levels. Insufficient vitamin D can cause dizziness because it plays a role in maintaining blood pressure and fluid balance.
Magnesium is a critical factor in making Vitamin D bioavailable. Without magnesium present, Vitamin D is stored in the body and not used. The body depends on magnesium to convert Vitamin D into its active form within the body.
And our body needs vitamin D for essential functions, like immune system response; and its deficiency can lead to many uncalled situations like poor bone health and a belly bulge.
Growing evidence has demonstrated that vitamin D has a role in sleep regulation [12]. Specifically, vitamin D deficiency (VDD) can increase risk of sleep disorders and is associated with sleep difficulties, shorter sleep duration, and nocturnal awakenings in children and adults [13,14,15].
Humans with vitamin D deficiency exhibit muscle pain in muscles at multiple locations. However, the strongest association between vitamin D deficiency and pain is reported to occur in leg muscles (Heidari et al., 2010).
[9,10] Low vitamin D leads to bone abnormalities (e.g., osteomalacia, osteopenia, and osteoporosis) and worsens muscle strength. [11] In otherwise healthy individuals, fatigue can be a manifestation of low vitamin D levels and its impact on reduced maximum functioning of skeletal muscles via vitamin D receptors.
Vitamin deficiencies are a common cause of paresthesias. The B vitamins — vitamin B12 and vitamin B6 — are the most common ones. Deficiencies in copper, calcium, and magnesium can also lead to tingling in your hands and feet. Most of the time, correcting the deficiency can help reverse the symptoms.
Causes of Leg Fatigue or Heaviness
They include: Varicose veins: The leg veins become enlarged. Peripheral arterial disease (PAD): Buildup of fat deposits in the artery walls, thus, causing inadequate circulation of blood in the legs. Overtraining syndrome: Excess training or physical activities to improve performance.
Possible culprit: A vitamin or mineral deficiency
One possible reason for feeling tired, anxious, and weak is having low levels of iron, vitamin D, or B12. Many experts believe that a significant percentage of the U.S. population is deficient in vitamin D.
Possible causes include stroke, systemic diseases, inflammatory conditions, nerve damage, muscle disorders, and medication side effects. It is important to seek medical attention to determine the underlying cause and receive appropriate treatment.
