What Vitamin Deficiency Can Cause Mouth Ulcers?

Canker sores or Aphthous ulcers

Mouth ulcers, also known as canker sores or aphthous ulcers, can be caused by various factors, including local trauma, hormonal changes, stress, and certain medical conditions. While vitamin deficiencies can contribute to mouth ulcers in some cases, the specific vitamin deficiency most commonly associated with mouth ulcers is a deficiency in vitamin B12 (cobalamin).

Vitamin B12 plays a crucial role in maintaining the health of the oral mucosa (the lining of the mouth). A deficiency in vitamin B12 can lead to a condition called pernicious anemia, which is characterized by inadequate production of red blood cells due to the body’s inability to absorb vitamin B12 from the gastrointestinal tract. Along with anemia, pernicious anemia can manifest with symptoms such as fatigue, weakness, pale skin, shortness of breath, and neurological symptoms.

Mouth ulcers can occur as a result of the mucosal changes associated with vitamin B12 deficiency. Additionally, deficiencies in other B vitamins, such as folate (vitamin B9) and riboflavin (vitamin B2), may also contribute to the development of mouth ulcers.

It’s important to note that while vitamin deficiencies can be a factor in the development of mouth ulcers, they are not the only cause. Other factors, such as local trauma, certain medications, autoimmune conditions, and infections, can also contribute to the formation of mouth ulcers. If you experience recurrent or severe mouth ulcers, it’s essential to consult with a healthcare professional for proper evaluation and management.
