Vitamin D Deficiency and Its ManagementBy Spyros G.E. Mezitis, MD, PhD Vitamin D is very important for human well-being. It is associated with sun exposure and calcium metabolism. Eighty percent of people are Vitamin D deficient in the Northeast United States and over one billion people worldwide suffer from Vitamin D deficiency. Do you have these signs or
symptoms?
The ten important signs and symptoms of Vitamin D deficiency shown in studies that may also be associated with other disorders are the following: 1. Arthritic and muscle pain 2. Chronic pain 3. Chronic fatigue 4. Depression 5. Chronic sinusitis 6. Progression from prediabetes to diabetes and worsening of diabetes 7. Arterial hypertension 8. Excessive hair loss and head sweats 9. Bone fragility and osteoporosis 10. Poor wound healing Where is Vitamin D in the body and how does it work? · Vitamin D is found below the skin and is
activated by sunlight. It is processed by the liver to Vitamin D 25-OH and further activated by the kidneys after which Vitamin D 1,25-OH helps absorb calcium from food in the intestines. Calcium is important in muscle and nerve function, bone strengthening and hormone secretion.
How do you measure Vitamin D in the body? · Vitamin D 25-OH can be measured in the blood and above 30 ng/dL is considered normal. Studies have shown that clinical signs and symptoms improve if Vitamin D 25-OH blood levels are corrected to above 40 ng/dL.
How do you treat Vitamin D deficiency? · Sun exposure needs to be at least two hours daily for arms and legs between 11 am and 3 pm in warm areas of the world but with increased risk of skin cancer. · Food that is rich in Vitamin D includes fish like salmon and tuna, dairy products like milk, cheese, and yogurt, egg yolks, and dark green vegetables like spinach, kale, and broccoli. · Vitamin D3 supplements alone or in combinations with calcium come in tablets, capsules, and liquid forms that can be taken daily, weekly or monthly.
Patients with
clinical signs of Vitamin D deficiency should be tested and if the blood sample shows levels below 40 ng/dL, Vitamin D3 at a dose to be specified by a physician should be initiated. Vitamin D is a fat-soluble vitamin and the oral capsules should be taken with fatty food. The patient needs to follow with a physician and check the Vitamin D 25-OH blood level one month after starting Vitamin D supplementation. The clinical signs and symptoms listed earlier should significantly improve. Spyros G.E. Mezitis, MD, PhD
