1What this means
Introduction Diabetes is one of the most common health conditions in India today. It affects how your body uses glucose, also called blood sugar. Glucose gives energy to your body, but when blood sugar levels become too high, it can damage organs, nerves, eyes, kidneys, and the heart.
2Causes and risk factors
The two main types are Type 1 Diabetes and Type 2 Diabetes . Both conditions increase blood sugar levels, but they happen for different reasons. Knowing the difference can help with early diagnosis, proper treatment, and better long-term health.
3Symptoms to notice
In this guide, you will learn about the symptoms, causes, risk factors, diagnosis, treatment options, prevention methods, and lifestyle changes for both Type 1 Diabetes and Type 2 Diabetes.
Get urgent care if symptoms are severe
Severe pain, breathing difficulty, fainting, bleeding, confusion or rapidly worsening weakness should be treated as urgent.
4Tests and diagnosis
What Is Diabetes? Diabetes is a chronic disease that happens when the body cannot properly use or produce insulin.
5Care and next steps
Insulin is a hormone made by the pancreas. It helps sugar move from the blood into the cells for energy.
6Care and next steps
When insulin does not work properly or is not produced in enough amounts, sugar stays in the bloodstream. This causes high blood sugar levels.
7Care and next steps
The two most common forms are:
8Care and next steps
Type 1 Diabetes
9Care and next steps
Type 2 Diabetes
10Care and next steps
What Is Type 1 Diabetes? Type 1 Diabetes is an autoimmune condition. The body's immune system mistakenly attacks the insulin-producing cells in the pancreas.
11Care and next steps
As a result, the body produces little or no insulin.
12Care and next steps
People with Type 1 Diabetes need insulin injections or insulin pumps for survival.
13Care and next steps
It is commonly diagnosed in children, teenagers, and young adults, but it can occur at any age.
14Care and next steps
What Is Type 2 Diabetes? Type 2 Diabetes happens when the body becomes resistant to insulin or does not make enough insulin.
15Care and next steps
In the beginning, the pancreas tries to make extra insulin. Over time, it cannot keep up, and blood sugar levels rise.
16Care and next steps
Type 2 Diabetes is more common in adults but is now increasingly seen in younger people due to obesity, unhealthy eating, and lack of physical activity.
