Yeast infections often affect those who have weaker immunity such as those who are positive with Human Immunodeficiency Virus (HIV) / Acquired Immune Deficiency Symptoms (AIDS), cancer, and all other diseases that damage the immune system. As mentioned, the initial response of the body to yeast infection is skin inflammation and itchiness. Sometimes more severe symptoms appear such as a burning sensation and painful chaps.
With and oral yeast infection, untreated conditions may lead to the spread of the yeast throughout the mouth area, down to the esophagus, pharynx, and even to the small and large intestines. Yeast infection commonly infects the genital and anal area, one of the body parts least exposed to sunlight and air circulation. The symptoms are the same as redness of the skin, followed by inflammation and itchiness. A genital discharge may also appear if the condition has already escalated to something severe. While yeast naturally occurs in the body and will not cause any harm if the body controls its numbers by natural physiology (or through the immune system), things can become harmful if the growth of the yeast exceeds beyond the normal level. Even if the person does not have any health problems, yeast overgrowth may still happen. How is this possible? For example, cleaning the body with good, hygienic products regularly is good, but too much of these may also cause harm.
Taking birth control pills, hormonal therapy, and third generation antibiotics can also affect the body’s hormone production, and hormonal imbalance can cause yeast overgrowth especially in the genital area.
Though yeast infection is not really categorized as a sexually transmitted disease, it can infect another person through skin contact especially in the genital area.
