What are possible indicators of folate deficiency?

The correct response includes indicators such as pale eye membranes and a swollen tongue. Folate deficiency can lead to several clinical manifestations due to its role in DNA synthesis and repair, as well as in red blood cell formation.

Pale eye membranes, or conjunctival pallor, can indicate anemia, which may be a result of insufficient folate as it is essential for producing red blood cells. A swollen tongue, often described as glossitis, is a classic sign of folate deficiency and can also cause discomfort and difficulty in eating.

The other options contain symptoms that do not typically relate specifically to folate deficiency. While flatulence and diarrhea may be associated with various gastrointestinal issues, they are not primary indicators of folate deficiency. Redness and swelling of the mouth can indicate a variety of conditions but are not the most recognized signs of folate deficiency either.

Thus, the best choice highlights the most characteristic indicators of a deficiency in this important nutrient.
