For lots of people, sinus infections -- or sinusitis -- and asthma go together. According to the Asthma and Allergy Foundation of America, as many as half of all people with moderate to severe asthma also have chronic sinusitis.
Along with all the problems caused by asthma, having sinusitis can be tough to handle. It can make you feel sick and miserable. Without good treatment, it can last for months or even years. What's worse, one condition can worsen the other. Sinusitis has been associated with more severe cases of asthma. So, not only does having asthma increase the odds of getting a sinus infection, but a sinus infection can make your asthma harder to control.
When it comes to asthma and appetite, doctors and dietitians worry most about patients who eat too much, shun exercise for fear of becoming breathless, and end up being overweight.
But in a small minority of patients, poorly controlled asthma can leave them too breathless and fatigued to eat properly. Furthermore, a few asthma medications can cause upset stomachs or thrush infections in the mouth, leading to poor appetite.
But there's good news. There are lots of treatments available for both sinusinfections and asthma. And studies show that treating one condition often helps relieve the symptoms of the other. The key is to treat both conditions aggressively.
What Is Sinusitis?
While there are many sinuses in the body, the term is often used to refer to the paranasal sinuses. These are a group of four hollow cavities in your face, near the cheeks and eyes. They're connected to the nasal passageways and help warm up, moisten and filter the air you breathe in. Sinusitis is the swelling or infection of these sinuses.
Just like the lining of your nose, the sinuses can become irritated and swollen by allergens, viruses, or bacterial infection. Common triggers of sinusitis include:
A cold or viral infection
Air pollution and smog
Dry or cold air
When the tissue in the sinuses gets irritated, it produces mucus. If enough mucus and trapped air builds up, you feel painful pressure in the sinuses. These are the familiar signs of a sinus headache.
Symptoms of sinusitis vary, depending on which sinuses are affected. But some common signs are pain in these areas:
Usually, sinus infections are caused by viruses, like a cold virus. But if the sinuses have been blocked for too long, bacteria can invade, causing a secondary infection. Having multiple sinus infections can lead to chronic (long-term) sinusitis.
