Introduction
In general, oral thrush may be caused by underdeveloped immune systems in infants, reduced saliva production in the elderly, weakened immunity, diabetes, AIDS, and other conditions. It is important to maintain good oral hygiene, eat a balanced diet to strengthen immunity, avoid misuse of antibiotics, and clean the mouth regularly. If any discomfort occurs, prompt medical attention is recommended.

Oral thrush is usually caused by factors such as underdeveloped immune systems in infants, reduced saliva secretion in the elderly, low immunity, diabetes, and acquired immunodeficiency syndrome (AIDS). If discomfort occurs, timely medical consultation is recommended. Specific analyses are as follows:

1. Underdeveloped Immune System in Infants

Newborns and infants have immature immune systems, making them susceptible to Candida infection, which can lead to oral thrush. It is important to enhance nutritional support for infants to strengthen their immunity.

2. Reduced Saliva Secretion in the Elderly

In older adults, decreased salivary gland function leads to reduced saliva production and diminished natural oral cleansing ability, increasing the risk of oral thrush. Using artificial saliva substitutes regularly can help maintain oral moisture.

3. Weakened Immunity

When the body's immune function is compromised, such as in individuals with chronic diseases, Candida can proliferate excessively and invade the oral mucosa, causing oral thrush. It is essential to boost immunity through balanced nutrition, adequate sleep, and maintaining good oral hygiene.

4. Diabetes

Diabetes is often associated with low immunity, genetic factors, and other conditions. High blood glucose levels create a favorable environment for Candida growth, making diabetic patients more prone to oral thrush. Symptoms may also include thirst and frequent urination. Patients are advised to follow medical guidance in using medications such as metformin tablets, gliclazide modified-release tablets, and acarbose tablets to manage symptoms.

5. Acquired Immunodeficiency Syndrome (AIDS)

AIDS can be transmitted through blood, mother-to-child transmission, and other routes. Viral infection severely weakens the immune system, allowing Candida infections to become uncontrollable and leading to oral thrush, possibly accompanied by fever and fatigue. Under medical supervision, patients may use antifungal medications such as posaconazole oral suspension, voriconazole tablets, or itraconazole capsules to alleviate symptoms.

Maintaining good oral hygiene, eating a balanced diet to strengthen immunity, avoiding excessive use of antibiotics, and regular oral cleaning are important preventive measures against oral thrush and other oral health issues.

Can sodium bicarbonate solution treat thrush?
Candidiasis, also known as thrush, is an inflammation of the oral mucosa caused by infection with Candida albicans. Under favorable conditions, this fungus can overgrow in the oral cavity, leading to the formation of white patches on the oral mucosa, accompanied by symptoms such as pain and discomfort. When the affected areas are wiped and cleaned with a 2% to 4% sodium bicarbonate solution, it can effectively reduce local inflammation.

What is the likelihood of contracting HIV through oral infection?
If there are wounds in the mouth such as ulcers or bleeding gums, or if the partner's genitals are damaged, the virus may enter the bloodstream through exchange of bodily fluids. The receiving partner is at higher risk, as their oral mucosa may come into direct contact with semen or vaginal secretions. Studies show that the per-act risk of transmission through oral sex is approximately 0–0.04%, but this risk increases with factors such as the number of open wounds and the presence of other sexually transmitted infections.
