Which Deficiency Causes Mouth Ulcers?

Mouth ulcers, also known as canker sores, can be caused by various factors, and nutritional deficiencies are one possible cause. One specific deficiency that can contribute to the development of mouth ulcers is a deficiency in vitamin B12 (cobalamin).

Vitamin B12 deficiency can lead to a condition called megaloblastic anemia, which affects the production of red blood cells. In addition to anemia-related symptoms, vitamin B12 deficiency can cause changes to the oral mucosa (the lining of the mouth), leading to the development of mouth ulcers or sores. These ulcers can be painful and recurrent.

It’s important to note that while vitamin B12 deficiency is one potential cause of mouth ulcers, there are many other factors that can contribute to their development, including:

  • Trauma or injury to the mouth.
  • Food allergies or sensitivities.
  • Stress and emotional factors.
  • Hormonal changes.
  • Viral infections.
  • Certain medications.
  • Autoimmune conditions.

If you frequently experience mouth ulcers or have any concerns about your oral health, it’s advisable to consult with a healthcare professional or dentist for a proper diagnosis and appropriate management. If a nutritional deficiency is suspected, they can recommend appropriate testing and treatment, which may include dietary changes or supplementation as necessary.
