Introduction
There is no saying that black tongue coating warns of four specific diseases. A black tongue coating may result from conditions such as oral ulcers, gastritis, or diabetes. The sores caused by oral ulcers are typically grayish-white or yellow, with a red halo around the surrounding mucosal tissue, creating a shadowed appearance at the ulcer site. Patients can use medications such as compound chamomile lidocaine gel or Bingbor powder under the guidance of a doctor.
There is no established medical advice suggesting that black tongue coating indicates exactly four specific diseases. A black tongue coating may result from conditions such as oral ulcers, gastritis, diabetes, and other causes, analyzed as follows:
1. Oral Ulcers
The sores in oral ulcers are typically grayish-white or yellow, with a red halo around the surrounding mucosal tissue, creating a shadowed appearance at the lesion site. Under medical guidance, patients may use medications such as compound chamomile lidocaine gel or Bingbor powder for treatment.
2. Gastritis
Gastritis leads to abnormalities in the gastrointestinal environment, affecting digestion and absorption of food, which may consequently cause discoloration of the tongue. Patients may follow medical advice to take medications such as amoxicillin capsules or omeprazole enteric-coated capsules.
3. Diabetes
Diabetes can disrupt the body's internal environment, impairing metabolism and excretion, leading to changes in skin color on the tongue, general fatigue, and other symptoms. Patients may follow medical recommendations to use medications such as acarbose tablets or repaglinide tablets.
In addition to the above causes, black tongue coating could also be caused by kidney stones, renal failure, poisoning, or other conditions. If any physical discomfort occurs, it is recommended to seek timely medical evaluation to rule out potential underlying diseases.
