Study Notes
Principles of endocrinology
- Endocrinology is the study of hormones and their effects on the body
- Hormones are chemical messengers produced by glands, that travel through the bloodstream to target cells, influencing various bodily functions
- Diabetes mellitus is a chronic condition characterized by high blood sugar levels, due to either insufficient insulin production (type 1) or resistance to insulin's effects (type 2)
- Hyperglycemic crises are life-threatening episodes of extremely high blood sugar, often requiring immediate medical attention
- Hypoglycemia is the condition of low blood sugar levels, which can be caused by various factors including inadequate food intake or excessive insulin
- Insulin is a hormone produced by the pancreas, essential for regulating blood sugar by allowing glucose to enter cells for energy
- Antidiabetic drugs are medications used to manage diabetes, aiming to lower blood sugar levels and improve insulin sensitivity
- Inpatient management of hyperglycemia focuses on controlling blood sugar levels in hospitalized patients with diabetes, often involving insulin therapy and strict monitoring
Dyslipidemias and disorders of lipoprotein metabolism
- Lipids are fats and cholesterol, essential for cell function and hormone synthesis, but high levels can contribute to cardiovascular disease
- Lipid disorders refer to abnormal levels of lipids in the blood, including elevated cholesterol, triglycerides, and low levels of HDL ("good") cholesterol
- Statins are a class of drugs commonly used to lower LDL ("bad") cholesterol by inhibiting the liver's production of cholesterol
- Second-line lipid-lowering agents are used when statins are ineffective or not tolerated, including fibrates, niacin, ezetimibe, and PCSK9 inhibitors
- Metabolic syndrome is a cluster of abnormalities, including high blood pressure, high blood sugar, elevated triglycerides, low HDL cholesterol, and abdominal obesity, significantly increasing the risk of heart disease and diabetes
Obesity and metabolism
