What Is Vitamin D Deficiency?

Vitamin D deficiency (also known as hypovitaminosis D) occurs when the level of vitamin D in the blood is lower than normal. Vitamin D is essential for:

• Calcium absorption

• Bone strength

• Muscle function

• Nerve health

• Immunity

Low levels can silently worsen pain conditions and delay recovery from spine, joint, and muscle disorders.

Why Is Vitamin D Deficiency So Common in India?

Even in sunny regions like West Bengal, vitamin D deficiency is extremely prevalent due to:

• Limited sun exposure (indoor lifestyle, office work)

• Use of sunscreens and covered clothing

• Darker skin tone reducing vitamin D synthesis

• Poor dietary intake

• Obesity and advancing age

At Rajarhat Pain Clinic, vitamin D deficiency is frequently identified in patients with chronic back pain, knee pain, shoulder pain, and generalized body ache.

Symptoms of Vitamin D Deficiency

Vitamin D deficiency symptoms can be subtle or severe:

• Persistent bone pain

• Muscle cramps and weakness

• Back pain and neck pain

• Joint stiffness

• Easy fatigue

• Increased risk of fractures

• Delayed recovery from pain treatments

In long-standing cases, hypovitaminosis D may worsen conditions like osteoporosis, lumbar spondylosis, and chronic pain syndromes.

Vitamin D Deficiency and Chronic Pain – The Hidden Link

Many patients continue to suffer from pain despite physiotherapy, medicines, or injections. One overlooked cause is vitamin D deficiency.

Low vitamin D levels can:

• Reduce muscle strength

• Increase pain sensitivity

• Delay healing

• Reduce response to pain procedures

That is why Dr. Chinmoy Roy routinely evaluates vitamin D status while treating pain patients.

Vitamin D Supplementation – When and How?

Who Needs Vitamin D Supplementation?

• Patients with confirmed vitamin D deficiency

• Elderly individuals

• Patients with chronic musculoskeletal pain

• Postmenopausal women

• Patients with limited sun exposure

Forms of Vitamin D Supplementation

• Oral tablets or capsules

• Sachets

• Injectable vitamin D (in selected cases)

⚠️ Important: Vitamin D supplementation should always be taken under medical supervision. Over-supplementation can be harmful.

How Much Vitamin D Is Needed?

The dose of vitamin D supplementation depends on:

• Blood vitamin D level

• Age

• Body weight

• Associated medical conditions

In his patient education video, Dr. Roy explains why self-medication for vitamin D deficiency is not recommended and why proper testing is essential.

Can Sunlight Correct Vitamin D Deficiency?

Sunlight helps, but in many patients, sunlight alone is not sufficient to correct vitamin D deficiency, especially in:

• Elderly patients

• Obese individuals

• Patients with chronic pain and spine problems

Hence, vitamin D supplementation becomes necessary.
