Potential symptoms of low vitamin D
Although having a low level of vitamin D is often asymptomatic, you might experience:
- More frequent infections
- Muscle or bone discomfort
- Depressed mood
If you have any of the following symptoms that are, or can be, associated with a vitamin D deficiency, then you should consult with your health-care practitioner:
- Muscle spasms and twitching (which can be anywhere but are more common in the face and around the mouth or eyes)
- Generalized weakness
- Loss of balance/falling
- Severe bone and joint pain – hip pain is most common
- Unexplained fracture
- An onset of seizures
- Abnormal heart rate or rhythm
- High blood pressure
Potential symptoms of high vitamin D
Although having a vitamin D level that is too high can be asymptomatic, with a very high level (usually a result of excess calcium absorption) you could experience:
- Anorexia/loss of appetite
- Diarrhea and/or constipation
- Excessive thirst, dry mouth
- Frequent urination
- Muscle cramping/pain/twitching
- Bone pain
- Nerve pain (neuropathy)
- Kidney stones
- Confusion and weakness
- Chest pain, irregular heart beat
- Elevated blood pressure
- Cough, shortness of breath
If you suspect you might have an excess level of vitamin D (which only occurs with excessive supplementation and is very uncommon), then you should consult with your health-care practitioner.
