16. Lung Problems

Lung Cancer

COVID-19 is mainly a respiratory illness, so lungs that already have issues can be susceptible to the virus. The medications used to treat these lung problems can also become risk factors, so people with lung problems must consult a physician regarding COVID. Some lung conditions that place people most at risk are the following: 

  • Asthma
  • Chronic obstructive pulmonary disease (COPD)
  • Lung cancer
  • Cystic fibrosis
  • Pulmonary fibrosis
  • Heavy smoking or vaping 

15. Cardiovascular Disease


The heart works in conjunction with the lungs to provide the body with oxygen. When the lungs are hurt, the heart can also be affected. The heart has to work harder, causing strain. Cardiovascular conditions can also prevent the body from fighting off the coronavirus, putting people more at risk. Lastly, the coronavirus may cause heart failure and arrhythmias even in people without heart diseases. Some of the following cardiovascular diseases are: 

  • Heart failure
  • Coronary artery disease
  • Pulmonary hypertension

14. Type 2 Diabetes and Obesity


Both type 2 diabetes and obesity can lower a person’s immune system. People who have type 2 diabetes are more prone to infections in general, because of the amount of sugar in their blood. Obesity can impair the lungs and heart as well as the immune system.
