Complications
By Mayo Clinic staffBeing deficient in vitamins increases your risk of many health problems:
- Pregnancy complications. Pregnant women with folate deficiency may be more likely to experience miscarriage and deliver babies that are premature or are smaller than average. A developing fetus that doesn't get enough folate from its mother can develop birth defects of the brain and spinal cord. If you're thinking of becoming pregnant, ask your doctor whether you should consider taking folic acid supplements, so your body's stores of folate will be enough to support your baby.
- Nervous system disorders. While vitamin B-12 is important for the production of red blood cells, it's also important for a healthy nervous system. Untreated, vitamin B-12 deficiency can lead to neurological problems, such as persistent tingling in your hands and feet. It can lead to mental confusion and forgetfulness, because vitamin B-12 is necessary for healthy brain function. Without treatment for vitamin B-12 deficiency, neurological complications can become permanent. Vitamin B-12 deficiency can cause these and other health problems before it leads to anemia.
- Scurvy. Vitamin C deficiency can lead to scurvy. Signs and symptoms of this rare disease include bleeding under the skin and around the gums.
