Blood sugar, also known as blood glucose, refers to the concentration of glucose (a type of sugar) present in the bloodstream. Glucose is the primary source of energy for the body’s cells and is obtained from the food we eat, especially carbohydrates. After digestion, glucose is absorbed into the bloodstream and carried to various cells throughout the body.
The level of blood sugar is regulated by a complex interplay of hormones, primarily insulin and glucagon, produced by the pancreas. Insulin helps lower blood sugar levels by promoting the uptake of glucose into cells, where it can be used for energy or stored for later use. Glucagon, on the other hand, increases blood sugar levels by prompting the liver to release stored glucose.
Having blood sugar levels within a healthy range is essential for overall health and well-being. Persistently high blood sugar levels, known as hyperglycemia, can be a sign of diabetes or insulin resistance. Conversely, consistently low blood sugar levels, known as hypoglycemia, can lead to symptoms like dizziness, shakiness, confusion, and in severe cases, loss of consciousness.
The standard unit for measuring blood sugar is milligrams per deciliter (mg/dL) in most countries. Normal fasting blood sugar levels typically range between 70 mg/dL to 99 mg/dL. After consuming a meal, blood sugar levels may temporarily rise but should return to normal ranges within a few hours.
Monitoring and managing blood sugar levels are crucial for individuals with diabetes to prevent complications and maintain their health. This involves a combination of medication (for some cases), dietary adjustments, regular exercise, and blood sugar testing. If you have concerns about your blood sugar levels, it is essential to consult with a healthcare professional for proper evaluation and management.
Hearing loss refers to the partial or total inability to hear sounds in one or both ears. It can affect people of all ages and can be temporary or permanent. There are three main types of hearing loss:
- Conductive Hearing Loss: This type of hearing loss occurs when there is a problem in the outer or middle ear that prevents sound from passing through to the inner ear properly. Common causes include ear infections, fluid buildup, earwax blockage, or problems with the ear bones (ossicles). Conductive hearing loss can often be treated medically or surgically.
