Tongue Manifestations of Anemia: Key Clinical Signs
Pallor of the Tongue and Oral Mucosa in Anemia
Pallor of the tongue and oral mucosa is one of the most common and early signs of anemia, especially iron deficiency anemia (IDA) and hemolytic anemia. Studies consistently report a high prevalence of mucosal and tongue pallor among anemic patients, with rates as high as 74–97% in different populations Alsheikh2019Yusuf2016Amin2025+3 MORE. This pallor results from reduced hemoglobin levels, leading to decreased blood flow and oxygenation in the oral tissues.
Glossitis and Atrophic Glossitis in Anemia
Glossitis, characterized by inflammation, redness, and swelling of the tongue, is a frequent manifestation in various types of anemia, particularly IDA. Atrophic glossitis, where the tongue appears smooth and shiny due to loss of papillae, is also commonly observed. Prevalence rates for glossitis and atrophic glossitis range from 11% to 36% in anemic patients Alsheikh2019Surachman2022Amin2025+4 MORE. Patients may report a burning sensation, pain, or discomfort, especially when eating spicy or hot foods Surachman2022Pires2020Idan2024.
Fissured Tongue and Geographic Tongue
Fissured tongue, marked by grooves or cracks on the tongue surface, is less common but still reported in some cases of anemia, with prevalence rates around 6–24% Balamanikandan2024Alsheikh2019Amin2025+1 MORE. Geographic tongue, characterized by irregular, map-like patches on the tongue, is rare but has been documented in both IDA and thalassemia patients Alsheikh2019Abdulkarim2023.
Burning Sensation and Glossodynia
A burning sensation of the tongue (burning mouth syndrome) and glossodynia (painful tongue) are notable symptoms in anemic individuals. These symptoms are reported in 2–10% of patients and are often associated with glossitis or atrophic changes Hidayat2017Alsheikh2019Surachman2022+4 MORE.
Candidiasis and Other Lesions
Candidiasis, a fungal infection presenting as white patches or soreness on the tongue, is frequently seen in anemic patients, particularly those with compromised immunity such as HIV/AIDS. Other less common tongue and oral lesions include angular cheilitis (cracking at the mouth corners), recurrent aphthous ulcers, and oral pigmentation Hidayat2017Alsheikh2019Amin2025+4 MORE.
Clinical Relevance and Early Detection
Tongue and oral manifestations can be among the first signs of anemia, sometimes appearing before systemic symptoms. Dentists and healthcare providers should be vigilant for these changes, as early recognition can prompt further investigation and timely management of underlying hematological disorders Balamanikandan2024Yusuf2016Tantray2020+1 MORE.
Conclusion
Anemia, especially iron deficiency anemia, often presents with distinct tongue manifestations such as pallor, glossitis, atrophic glossitis, fissured tongue, burning sensations, and, less commonly, candidiasis and geographic tongue. These oral signs are valuable clinical indicators and can aid in the early detection and management of anemia.
