Candida infection occurs in patients with serious underlying diseases and low immunity, such as inhibiting the normal flora in the body after abusing antibiotics, and the infection is triggered by the proliferation of Candida. Doing some invasive medical operations can also cause Candida infection. Fungal infections caused by various pathogenic Candida are Candida infections, which are prevalent in immunocompromised people. Candida can invade the skin, mucous membranes, tissues and organs of the whole body. Candida invades and spreads in different parts of the body, and the symptoms shown by the body are not the same. The habit of abusing antibiotics may inhibit the normal flora in the body, which is conducive to the colonization and reproduction of Candida in the body, thus causing Candida infection. Doing some invasive medical operations, such as various surgeries, inserting stomach tubes, inserting urinary catheters, can provide opportunities for Candida to invade the body, which can also cause Candida infections. Candida infections should be treated promptly and according to the individual’s condition under the guidance of the doctor.
