As already mentioned, the primary cause of vitamin C deficiency is an imbalanced diet. This is because the human body does not naturally synthesise vitamin C, and it has to be supplied via external sources. This primarily concerns food intake, including vegetables, fruits, and fortified foods.
This is why most causes of deficiency of vitamin C involve an improper diet. Some of these are as follows:
- A diet lacking vitamin C-rich fresh vegetables and fruits
- A restrictive diet due to health conditions like weak digestive system, allergies, etc.
- Mental health issues and other disorders like anorexia
- Old age
Besides, there can be a number of other causes for lack of vitamin C. These include treatments, health conditions, and habits that limit the body’s ability to absorb nutrients. Some of them are as follows:
- Ulcerative colitis
- Intake of illegal drugs and high amounts of alcohol
- Crohn’s disease
- Prolonged diarrhoea
These factors can lead to a long-term condition of vitamin C deficiency, which might lead to detrimental side effects.
