Diabetes Mellitus: Types, Causes, Symptoms, Treatment, and Diet

The body relies on glucose as an essential energy source for cells in muscles, tissues, and the brain. Insulin, a hormone released by the pancreas, regulates blood glucose levels. However, individuals with diabetes experience either insufficient insulin production by the pancreas or resistance of the body's cells to insulin, leading to elevated blood glucose levels, commonly referred to as high blood sugar.

Types of diabetes include:

1. Type 1 diabetes: Characterized by an absolute lack of insulin production, it's a chronic condition where the pancreas generates minimal or no insulin.

2. Type 2 diabetes: Involves insufficient insulin use and insulin resistance. Initially, the pancreas produces extra insulin, but over time, it becomes inadequate to maintain normal blood glucose levels.

3. Gestational diabetes: Occurring during pregnancy, it involves elevated blood sugar levels in a woman without diabetes, usually resolving after childbirth. More common in the second half of pregnancy.

Diabetes risk factors:

Diabetes risk factors include a family history, obesity, age over 45, sedentary lifestyle, and other conditions like pancreatic diseases or polycystic ovary syndrome. Common symptoms encompass unintentional weight loss, persistent fatigue, blurred vision, excessive thirst, and frequent urination. Complications may lead to heart disease, nerve damage, kidney issues, retinal damage, infections, and hearing impairment. Uncontrolled diabetes poses risks during pregnancy, affecting newborns and pregnant women. Consult a doctor promptly for early detection, especially with increased risk or noticeable symptoms, to manage blood glucose levels and prevent complications. Regular checkups with an endocrinologist are crucial in diabetes care.

Diabetes diagnosis:

Diabetes diagnosis involves a comprehensive assessment by a diabetologist or endocrinologist, considering signs, symptoms, medical history, and physical examination. Tests include HbA1c, fasting plasma glucose, and random plasma glucose. Normal blood sugar levels for those without diabetes range from 70–99 mg/dL (3.9–5.5 mmol/L) fasting and less than 140 mg/dL (7.8 mmol/L) 2 hours after a meal. ADA recommends 80–130 mg/dL (4.4–7.2 mmol/L) for diabetics post-fasting. During pregnancy, fasting sugar should be below 95 mg/dL, and 2 hours after a meal, it should be less than 120 mg/dL. A normal HbA1c level is between 4% and 5.6%, while 6.5% or higher indicates diabetes.

Overview of Diabetes:

1- Definition:

Diabetes Mellitus encompasses types, causes, symptoms, treatment, and diet.

2- Inquiry:

What would you like to know about diabetes?

3-  Essence of Diabetes Mellitus:

 The body relies on glucose for energy, regulated by insulin. In diabetes, the pancreas fails to produce enough insulin or cells become resistant, causing elevated blood glucose levels (high blood sugar).

4- Types of Diabetes:

  - Type 1: Absolute lack of insulin production.

  - Type 2: Insufficient insulin use and resistance.

  - Gestational: Occurs during pregnancy, often resolving post-birth.

5-  Diagnosis and Norms: 

A diabetologist evaluates signs, symptoms, medical history, and conducts tests such as HbA1c, fasting plasma glucose, and random plasma glucose. Normal blood sugar levels vary, with HbA1c levels indicating diabetes.

6-  Risk Factors and Symptoms:

 Family history, obesity, age, sedentary lifestyle, and other conditions increase diabetes risk. Symptoms include unintentional weight loss, fatigue, blurred vision, excessive thirst, and frequent urination.

7- Complications: 

Untreated diabetes can lead to severe complications such as heart disease, neuropathy, foot damage, kidney issues, and eye problems.

Damage to the eye's retina, known as retinopathy, can lead to severe consequences such as blindness, cataracts, and glaucoma. Skin infections, including bacterial and fungal types, may result from non-healing wounds. Uncontrolled diabetes carries various risks, including: newborn defects, often indicated by a birth weight of 4 or 4.5 kg or more, termed "large for gestational age"; low blood sugar (hypoglycemia); increased risk of type 2 diabetes; and fetal death. Pregnant women face complications such as preeclampsia, a potentially life-threatening condition linked to high blood pressure, increased urine protein, and general swelling. Future pregnancies elevate the risk of gestational diabetes and type 2 diabetes. Timely consultation with a doctor or endocrinologist is crucial for those at risk. Symptoms like frequent urination, excessive thirst, or sudden weight loss should prompt immediate attention. Regular checkups with an endocrinologist aid in monitoring blood glucose levels and preventing diabetes-related complications. Diagnosis involves signs, symptoms, medical history, physical exams, and specific tests. Normal blood sugar levels are: fasting (70–99 mg/dL for non-diabetic individuals, ADA recommends 80–130 mg/dL for those with diabetes); 2 hours after a meal (less than 140 mg/dL for non-diabetics, ADA recommends less than 180 mg/dL for those with diabetes); and during pregnancy (fasting less than 95 mg/dL, 2 hours after eating less than 120 mg/dL). The normal HbA1c level ranges from 4% to 5.6% for individuals without diabetes. Levels between 5.7% and 6.4% indicate a higher diabetes risk, while 6.5% or higher signifies diabetes.

What is the treatment of diabetes?

Physicians or endocrinologists guide diabetes treatment, considering options like oral medications, insulin, and lifestyle changes such as exercise and dietary adjustments. Weight loss surgery might be recommended. Due to complication risks, managing related health factors like blood pressure and cholesterol is advised. While diabetes lacks a cure, prevention involves controlling risk factors—steps like weight loss, regular exercise, a low-calorie diet, quitting smoking, and moderating alcohol intake. A "diabetes diet" varies, emphasizing healthy, nutritious choices. Limiting fried foods and sugary drinks, avoiding excessive alcohol, and customizing the diet with medical guidance aids blood sugar control, along with monitoring for triggers like diet, exercise, medications, stress, and hormonal changes.

Consider factors affecting blood sugar: High-fat meals prolong elevated sugar levels. Monitor sugar load, focusing on calorie count and total carbs per serving, as they directly impact blood sugar. Avoid overeating; opt for smaller, frequent meals for stable sugar levels. Moderate alcohol intake hampers insulin response, complicating hyperglycemia control in individuals with diabetes.
