lately I've been wondering, is atherosclerosis considered a symptom or a disease itself? I looked it up on google and found that it's considered a condition, and a condition is anything that affects how we live or work, which sounds a lot like a symptom to me. Considering allergies, its symptoms are typically sneezing, a runny nose, etc. These are our bodies natural reactions to certain stimuli. But atherosclerosis is caused by actual harm done to the body over time, so it can't possible be considered a symptom right? Is atherosclerosis a disease that cause other diseases?
