Diabetes, also known as diabetes mellitus, is a metabolic condition caused due to high blood sugar. Our pancreas produces a hormone known as insulin that helps move sugar from the blood into the cells, giving them energy. When a person suffers from diabetes, their body either does not produce enough insulin or is unable to use the hormone effectively.

When diabetes goes untreated, it can damage your nerves, eyes, kidneys, and other vital organs as well. You should know diabetes types before moving on to the details of the said health condition.

Types of Diabetes

1. Type 1 Diabetes

Diabetes type 1 is an autoimmune condition. Here, the immune system attacks and damages the cells in the pancreas. While it is still unclear why the attack happens, several people in India mainly suffer from this diabetic condition.

2. Type 2 Diabetes

Diabetes type 2 is a health condition developed when the body becomes resistant to insulin. Here, the sugar levels in the blood keep increasing, further causing harm to several vital organs in the body.

3. Prediabetes

This is one of the diabetes types that occurs when blood sugar becomes higher than the normal range. However, blood sugar levels are not high enough to be diagnosed with diabetes type 2, as explained above.

4. Gestational Diabetes

This condition arises when the blood sugar level increases during pregnancy. It is caused due to the insulin-blocking hormones produced by the placenta.

Diagnosis of Diabetes

If anyone is experiencing diabetes symptoms or is at risk of developing the condition should get themselves tested. Pregnant women should check their blood sugar levels during routine checkups, especially during the second or third trimester. The doctors can use blood tests to diagnose diabetes and prediabetes.

  • The fasting plasma glucose (FPG) test helps measure the blood sugar in the body after the patient has fasted for eight hours.
  • The A1C test provides a snapshot of blood sugar in the body for the last three months.

When it comes to gestational diabetes, doctors suggest testing blood sugar during the 24th or 28th weeks of pregnancy. The earlier can detect diabetes mellitus, the earlier you will be able to start the treatment.

Treatment for Diabetes

The treatment for diabetes mellitus depends on its type. Let us take a look at the same.

1. In the case of Diabetes Type 1

Insulin is the primary treatment for type 1 diabetes. It replaces the hormone your body is unable to produce. Doctors use four types of insulin that are differentiated based on how effectively they work.

  • Rapid-Acting Insulin: Usually starts to show effect within 15 minutes and lasts for 3-4 hours.
  • Short-Acting Insulin: Starts to show effect within 30 minutes and lasts for 6-8 hours.
  • Intermediate-Acting Insulin: Starts to show effect within 1-2 hours and lasts for 12-18 hours.
  • Long-Acting Insulin: Starts to show effect within a few hours after injection and lasts for up to 24 hours or more.

Your doctor will recommend either one of these, depending on the severity of your diabetes condition.
