symptoms of Diabetes

We need to know about ‘What are Symptoms of Diabetes’. In India, according to World Health Organization Stats, there are more than 77 Million / ~ 7.7 Cr people suffering from Diabetes & around 2.5 Cr people are about to have diabetes. No one knows who’s going to be next.

This is why, in this blog, we have added all the information about ‘What are the Symptoms of Diabetes?’ After reading this blog, You’ll be able to recognize the factors, cures, and symptoms of Diabetes. To prevent Diabetes, we have to recognize its symptoms in the very first place. This blog will help you with that.
So, let’s start-

What is Diabetes?

Diabetes is a chronic health condition characterized by elevated levels of blood sugar, or glucose. The underlying issue is either insufficient insulin production (Type 1) or ineffective use of insulin by the body (Type 2). This results in disrupted glucose regulation, leading to a range of symptoms and potential complications affecting various organ systems.

Types of Diabetes

There are mainly three types of Diabetes:
Type – 1
Type – 2
Gestational Diabetes

We have added all the explanations about all types below-

Type 1 Diabetes


Type 1 diabetes is an autoimmune condition where the body’s immune system mistakenly attacks and destroys insulin-producing beta cells in the pancreas. The exact cause of this immune response is not fully understood, but it is believed to involve a combination of genetic and environmental factors.


Typically diagnosed in childhood or adolescence, although it can occur at any age.


  • Excessive thirst (polydipsia)
  • Frequent urination (polyuria)
  • Unexplained weight loss
  • Fatigue
  • Increased hunger (polyphagia)


Blood tests measure blood glucose levels and, sometimes, additional tests to detect antibodies associated with the autoimmune destruction of beta cells.


Life-long insulin therapy is essential for individuals with Type 1 diabetes, as their bodies cannot produce insulin. Insulin is usually administered through injections or an insulin pump. The dosage is tailored to match food intake, physical activity, and blood glucose levels.


Regular monitoring of blood glucose levels is crucial to adjust insulin doses and maintain stable blood sugar levels. Continuous glucose monitoring systems and periodic HbA1c tests provide valuable insights into long-term glucose control.


If not well-managed, Type 1 diabetes can lead to complications such as heart disease, kidney damage, nerve problems, and vision issues. Close medical supervision and a proactive approach to lifestyle and treatment are essential to prevent and manage these complications.

Lifestyle Considerations

Individuals with Type 1 diabetes need to carefully manage their diet, exercise regularly, and maintain a healthy lifestyle. Education about carbohydrate counting, insulin adjustment, and response to illness or stress is vital for effective self-management.

Type 2 Diabetes


Type 2 diabetes is characterized by insulin resistance, where the body’s cells do not respond effectively to insulin, and eventually, the pancreas may not produce enough insulin. The exact cause is multifactorial, involving genetic predisposition, lifestyle factors, and obesity.


Typically diagnosed in adulthood, but increasingly seen in children and adolescents, especially with rising obesity rates.


  • Increased thirst (polydipsia)
  • Frequent urination (polyuria)
  • Blurred vision
  • Fatigue
  • Slow wound healing
  • Recurrent infections


Blood tests measuring fasting blood glucose, oral glucose tolerance test (OGTT), and HbA1c levels.


  • Lifestyle Changes: Dietary modifications, regular physical activity, and weight management are fundamental. A balanced diet, rich in whole foods, and low in processed sugars is crucial.
  • Oral Medications: Various medications may be prescribed to improve insulin sensitivity, stimulate insulin production, or reduce glucose absorption in the digestive tract.
  • Insulin Therapy: In some cases, insulin injections may be necessary, especially as the disease progresses.


Regular monitoring of blood glucose levels is essential. Lifestyle adjustments and medication doses may need modification based on these measurements.


Type 2 diabetes, if not well-managed, can lead to complications such as cardiovascular disease, kidney problems, nerve damage, and vision impairment. Controlling blood sugar levels, along with managing blood pressure and cholesterol, is critical to preventing complications.


Type 2 diabetes is often preventable through maintaining a healthy lifestyle, including a balanced diet, regular physical activity, and weight management. Early detection and intervention can also significantly impact disease progression.

Gestational Diabetes


Gestational diabetes develops during pregnancy when the body cannot produce enough insulin to meet the increased needs, leading to elevated blood glucose levels.

Risk Factors

  • Obesity: Overweight women are at a higher risk.
  • Family History: A family history of diabetes increases susceptibility.
  • Maternal Age: Advanced maternal age is associated with a higher risk.
  • Ethnicity: Some ethnic groups, including African American, Hispanic, Native American, and Asian American, are more prone.


  • Gestational diabetes often has no noticeable symptoms, but some women may experience:
  • Increased thirst
  • Frequent urination
  • Fatigue


Screening for gestational diabetes usually occurs between 24 and 28 weeks of pregnancy. It involves an oral glucose tolerance test (OGTT) where the woman drinks a sugary solution, and blood glucose levels are measured at intervals.


  • Dietary Changes: Emphasizing a balanced diet, focusing on complex carbohydrates, and avoiding excessive sugar intake.
  • Physical Activity: Regular exercise helps control blood sugar levels.
  • Monitoring: Regular blood glucose monitoring is essential to ensure levels remain within a healthy range.
  • Insulin Therapy: If blood sugar levels cannot be adequately controlled through lifestyle measures, insulin therapy may be recommended.


Gestational diabetes poses risks for both the mother and the baby. Complications may include:

  • Maternal Risks: Increased likelihood of developing Type 2 diabetes later in life and potential complications during delivery.
  • Fetal Risks: Higher risk of macrosomia (large birth weight), birth injuries, respiratory distress syndrome, and an increased chance of developing obesity and Type 2 diabetes later in life.

Postpartum Monitoring

Women with gestational diabetes should undergo postpartum glucose testing to ensure blood sugar levels return to normal. They are also encouraged to maintain a healthy lifestyle to reduce the risk of developing Type 2 diabetes in the future.

Diabetes Symptoms in Men & Women

Diabetes Symptoms can be seen in both Men and Women. Sometimes it could be the same but not all the time. We have added a detailed overview below-

Common Symptoms

  • Increased Thirst (Polydipsia): Individuals with diabetes may experience excessive thirst as the body attempts to eliminate excess glucose through increased urination.
  • Frequent Urination (Polyuria): Elevated blood glucose levels prompt the kidneys to work harder to filter and remove excess sugar, leading to increased urine production.
  • Fatigue: The body’s inability to efficiently utilize glucose for energy can result in persistent fatigue and weakness.
  • Unexplained Weight Loss: Despite increased appetite, individuals may lose weight due to the body breaking down muscle and fat for energy when glucose cannot be properly utilized.

Gender-Specific Symptoms

In Men

  • Erectile Dysfunction: Diabetes can impact blood flow and nerve function, contributing to erectile dysfunction in men.
  • Reduced Muscle Mass: Muscle wasting may occur due to the breakdown of protein for energy when glucose is not effectively used.

In Women

  • Yeast Infections: High blood sugar levels create a favorable environment for yeast growth, increasing the risk of recurrent infections, particularly in the genital area.
  • Polycystic Ovary Syndrome (PCOS): Women with diabetes, especially Type 2, may have an increased likelihood of PCOS, impacting fertility and hormonal balance.

General Symptoms in Both Genders

  • Blurred Vision: Fluctuating blood sugar levels can affect the eyes, causing blurred or distorted vision.
  • Slow Wound Healing: Diabetes impairs the body’s ability to repair and regenerate tissues, leading to delayed wound healing.
  • Numbness or Tingling (Neuropathy): Nerve damage due to prolonged high blood sugar can result in sensations of numbness, tingling, or pain, often in the extremities.

Complications of Diabetes

Acute Diabetes Complications:

1. Hypoglycemia

  • Cause: Low blood sugar levels, often due to excessive insulin, missed meals, or increased physical activity.
