Metabolism

From WikiMD's Wellness Encyclopedia

(Redirected from Metabolised)

Metabolism encompasses the myriad of physical, chemical, and biological operations within the body that require energy. This intricate system performs various tasks, from the cellular to the systemic levels. Its understanding provides insights into energy utilization, maintenance, and health implications, both physiological and pathological.

Fundamental Processes of Metabolism[edit | edit source]

The body undergoes numerous metabolic activities, crucial for vitality and functionality. Some key metabolic processes include:

Basal Metabolic Rate (BMR)[edit | edit source]

The BMR represents the energy quantum a person requires to remain weight-stable, neither losing weight nor gaining weight. It is the minimal energy necessary for essential physiological functions in a resting, post-absorptive state.

Metabolic Disorders[edit | edit source]

Metabolic disorders arise when typical metabolic pathways are disrupted, either due to hormonal imbalances or other factors. This disruption can lead to an excess or deficiency of specific substances vital for health. A prominent example is the metabolic syndrome, often considered a precursor (prediabetes) and can progress to type 2 diabetes through a mechanism known as insulin resistance.

Types of Metabolic Disorders[edit | edit source]

Some prevalent metabolic disorders include:

  • Metabolic syndrome: A cluster of conditions increasing the risk of heart disease, stroke, and type 2 diabetes.
  • Type 2 diabetes: A chronic condition affecting the way the body processes blood sugar (glucose).
  • Hypothyroidism: A condition where the thyroid gland does not produce enough thyroid hormones.

Genetic Disorders of Metabolism[edit | edit source]

Genetic metabolism disorders result from inherited defects affecting specific metabolic pathways. They can lead to an accumulation or shortage of certain substances in the body, causing various health issues. Examples include:

Factors Influencing Metabolism[edit | edit source]

Various factors modulate metabolism, impacting energy expenditure and utilization. Such factors encompass hormones, medications, nutritional status, growth, age, gender, temperature, and more. A frequently misunderstood metabolic influencer is insulin and its anabolic role in weight gain.
