rasvakertymään

Rasvakertymä refers to the accumulation of fat in the body. This can occur in various forms and locations, leading to different physiological outcomes. General obesity is characterized by an excess accumulation of adipose tissue throughout the body. This can be measured using body mass index (BMI), although it's important to note that BMI has limitations and doesn't distinguish between muscle and fat.

Localized fat deposits, often referred to as subcutaneous fat, can accumulate in specific areas, such as the abdomen, thighs, or buttocks. This type of fat is generally less metabolically active than visceral fat. Visceral fat, on the other hand, surrounds internal organs in the abdominal cavity. While not directly visible, increased visceral fat is strongly associated with a higher risk of developing chronic diseases like type 2 diabetes, heart disease, and certain cancers.

Factors contributing to fat accumulation include genetics, diet, physical activity levels, hormonal changes, and environmental influences. A positive energy balance, where calorie intake exceeds calorie expenditure, is the fundamental principle behind weight gain. Lifestyle modifications, including dietary changes and increased physical activity, are key strategies for managing and reducing fat accumulation. Medical conditions and certain medications can also influence fat distribution and storage. Understanding the different types and locations of fat accumulation is crucial for assessing health risks and developing appropriate management strategies.
