A chronic illness is a long-lasting condition that can persist for months or years, often requiring ongoing medical attention and management. These types of conditions are not typically curable but can be managed with medication, therapy, or lifestyle changes. Examples of chronic illnesses include diabetes, heart disease, arthritis, asthma, and many others. The severity of symptoms can vary over time, and individuals may experience periods of remission where their condition is under control, followed by flare-ups or worsening of symptoms. Chronic illnesses can have a significant impact on an individual's quality of life, but with proper management and support, many people are able to lead fulfilling lives despite their diagnosis.
