Recovering from a Respiratory Illness

Chances are you’ve experienced the symptoms of a respiratory illness in the past. Scratchy or sore throat, runny or stuffy nose, coughing… all are telltale signs of conditions that vary in severity, from minor colds to more serious viruses. But without the proper treatment, even seemingly harmless illnesses can result in lingering health problems, especially for those whose immune systems have been weakened. However, seeking treatment for illnesses early on can reduce the risk of long-lasting effects, leading to a faster recovery.

Long-term Side Effects of Respiratory Illness

Colds and flu may be regarded as minor illnesses, but for some, the consequences can be more serious than just sniffles and coughs; left untreated, some respiratory illnesses can have long-term effects, though the outcome can vary based on numerous factors, such as age, nutrition, and immune system strength. Lung damage can develop in the immediate aftermath of diseases like COVID-19, and studies have shown children hospitalized for respiratory syncytial virus (RSV) are 2-4 times more likely to develop asthma, though how and why are not fully understood.

Additionally, studies by the University of Michigan have found adult RSV patients had “poor physical functioning, functional impairment, and persistent problems” like shortness of breath six to 12 months after hospitalization; older adults were found to have higher risk of “losing at least one independent activity of daily living,” the study reported, while also concluding younger adults were at higher risk of “more significant sleep disturbances.” Research has also shown that influenza can not only cause complications for patients with diabetes but may in some cases trigger diabetes.

Who’s at the Greatest Risk?

Respiratory illnesses can affect people in different ways, but some populations are at higher risk for more severe effects.

Those considered at higher risk include:

Older adults — A combination of weakened immune systems and greater likelihood of underlying medical conditions makes older and elderly adults more vulnerable.

Young children — Infants and children have immune systems that are still developing. Coupled with smaller airways, this makes them more susceptible to respiratory infections.

Certain medical conditions — Underlying health conditions like heart disease or diabetes — in addition to weakened immune systems and some disabilities — can make respiratory viruses a greater threat.

Pregnancy — While pregnant, changes to the immune system, heart, and lungs can result in more serious complications from respiratory illnesses, which in turn may also affect the baby.

How to Treat Respiratory Illness

Your primary care provider should be your first contact when you begin feeling the effects of a respiratory illness. Your provider can determine the severity of your illness — from colds and sinus infections to influenza and COVID-19 — and provide a treatment plan to get you on the road to recovery. If symptoms are severe enough that you can’t wait for an appointment, a visit to the Walk-in Clinic can offer more immediate treatment. When symptoms become debilitating — e.g., your child’s chest is contracting or you have a persistent, high fever that won’t break — a visit to the Emergency Department is warranted. As you recover, symptoms may linger for days or even weeks; if these symptoms do not resolve over time, talk to your provider to find out if respiratory therapy could get you back to your previous quality of life.
