All human bodies have healthy bacteria in them. Some of these bacteria live in the upper respiratory tract and are usually harmless. If the body's defense mechanism weakens, the bacteria may divide uncontrollably and infect the sinuses. Once they affect the sinus, the symptoms of acute sinusitis appear. Other types of sinusitis are caused by fungi. These are mycetoma fungal sinusitis, allergic fungal sinusitis, chronic indolent sinusitis, and fulminant sinusitis. A weak immune system makes it possible for fungus to infect the body. Fungi usually favor dark and moist environments. The sinuses, which are naturally of moist and dark cavities, are a perfect environment for the fungi to breed. When fungal infection sets in on the sinus, then we have fungal sinusitis.Unfortunately, treating sinusitis fully can prove to be very difficult. Using antibiotics is an option; however, even after using these, symptoms may persist. The patient may also decide to control the symptoms of sinusitis by exploring alternative therapeutical medicine in curbing the menace of sinusitis as other medications like nasal spray and decongestants may cause side effects. Consequently, Steroids in nasal sprays may cause nosebleeds.An option for cases that will not be cured by medicine or herbal methods is endoscopic sinus surgery. A doctor will thoroughly examine the sinus passages using an endoscope and a thin, flexible tube with an attached light. Then, depending on the source of obstruction, the doctor may use various tools to remove tissue or shave away a polyp that's causing nasal blockage. Another alternative is to enlarge a narrow sinus opening which will then allow drainage.Individuals who seem to experience recurring instances of prolonged colds may actually have sinusitis. If one notices that a cold or allergy seems not to get cured, it is possible that the individual has sinusitis.
