Factors that contribute to vitamin deficiency:


Vitamin deficiency has a direct link to your diet. Vitamins are often included in fruits, vegetables, grains, meat, poultry and seafood. All these vitamins are found in more than one type of food, and many foods are more fortified with vitamins than others; for instance, milk has calcium (not a vitamin) and vitamin D.

Vitamin deficiency may occur if you’re not eating foods fortified with vitamins, like pasta, rice, cereals, etc.

Other causes of vitamin deficiency may include some medical conditions which have an adverse reaction when it comes to the absorption of vitamins; since our bodies don’t have the ability to vitamins, vitamin deficiency can occur within weeks. Therefore, visiting your healthcare professional regularly and getting vitamin tests done routinely is best.

Medical conditions that may cause vitamin deficiency may include:

  • Alcoholic liver disease
  • Liver failure
  • Kidney disease
  • Chronic diarrhea
  • Malabsorption syndrome
  • Gastric bypass
  • Inflammatory bowel disease
  • Crohn’s disease
  • Irritable bowel syndrome
  • Pernicious anaemia

Signs of vitamin deficiency:


Many vitamin deficiency symptoms go unnoticed, but you may see some signs; this is your body’s way of communicating that your body requires vitamins. Some of these signs may include the following:

  • Tiredness, low on energy.
  • Losing bone density
  • Dry skin and hair
  • Irritation
  • Depression
  • Getting bruised and starting bleeding easily.
  • Wounds take more time than usual to heal.
  • Predisposition to infections
  • Changes in skin colour. Small, light or flat patches may become visible.


Vitamin deficiency can cause more than one symptom, and many symptoms, like insomnia, may be due to different vitamin deficiencies. Vitamin testing is the only way to determine which vitamin your body lacks.

Vitamin test results and their diagnosis may take some time. Since vitamin testing is not that common, your healthcare provider may perform a physical exam to examine symptoms like skin discoloration, bruises not healing and neuropathy and determine if vitamin tests are needed.

If your test results suggest that you have a vitamin deficiency, your doctor may prescribe some supplements to you to help you maintain vitamin levels in a few days, or you may have to take them long-term.
