Type 2 diabetes occurs when the body fails to use insulin effectively or when it does not produce sufficient insulin to keep blood glucose levels within a healthy range. In some cases, people notice changes in their health prior to being diagnosed, whereas in others there are few or no symptoms in the early stages.

It is important to identify the condition early since prolonged high levels of blood glucose over a period raise the risk of various health problems. Should you notice any symptoms such as increased thirst, needing to go to the toilet more frequently, unusual tiredness, or unexpected changes in weight, seeing your practitioner will allow symptoms to be evaluated and appropriate testing to be arranged.

What Is Type 2 Diabetes?

Type 2 diabetes is a long-term condition which affects the way your body handles glucose, a substance that provides energy for the cells. Insulin acts to transfer glucose from the blood into the cells. If the body becomes less responsive to insulin, then blood glucose levels begin to increase.

The condition generally develops slowly, with lifestyle factors, family history, age, and other health conditions all affecting your personal risk.

What Are the Early Signs of Type 2 Diabetes?

The early symptoms differ from person to person. In some cases, the signs develop gradually and may be easily missed. Typical symptoms are:

• Increased Thirst

It is one of the possible indications of high blood glucose levels to be unusually thirsty, particularly when you have drunk more than normal yet still experience thirst.

• Frequent Urination

Another symptom associated with diabetes is needing to urinate more frequently, including having to get up during the night to use the toilet.

• Unexplained Weight Changes

Before they are diagnosed, some people suffer an unexpected loss in weight, even if they have not altered their diet or level of activity.

• Ongoing Fatigue

It is normal to feel tired after a busy day, but the kind of fatigue associated with diabetes tends to persist even when one has gotten sufficient rest.

• Blurred Vision

Alterations in blood glucose levels influence fluid balance in the eye and this may result in temporarily blurred vision.

• Slow-Healing Cuts or Wounds

Prolonged high levels of blood glucose interfere with circulation and the body’s capacity to deal with infections. As a result, some individuals find that cuts, sores, or skin injuries take longer to heal.

• Tingling or Numbness

People who have diabetes may experience a tingling, a burning, or a numbness in their hands or feet, since long-term high levels of blood glucose influence the nerves.

What Causes or Increases the Risk of Type 

Diabetes?

Type 2 diabetes results from a combination of genetic, lifestyle, and health factors.

• Family History

If one of your close family members has type 2 diabetes, your own risk goes up. The genes affect the way your body responds to insulin and handles glucose.

• Weight and Lifestyle Factors

Having extra weight, especially in the abdomen, is associated with an increased risk of insulin resistance.

• Age

The likelihood of getting type 2 diabetes rises as people get older, even though younger adults and children can also have the disease.

• Physical Inactivity

Routine movement helps to maintain proper regulation of blood glucose. If a person stays inactive for long periods, then the body’s efficiency in using glucose decreases.

• Other Risk Factors

Other factors linked with increased risk include:

• Previous gestational diabetes during pregnancy
• High blood pressure
• Polycystic ovary syndrome (PCOS)
• Abnormal cholesterol levels
• Certain ethnic backgrounds with higher diabetes risk

Can You Have Type 2 Diabetes Without Symptoms?

It is possible for some individuals to have type 2 diabetes without any obvious warning signs, in the early stages. Routine health checks aid in detecting changes before symptoms appear. When deciding if diabetes screening is suitable, the GP will consider your age, medical history, family history, and other risk factors.

How Is Type 2 Diabetes Diagnosed?

Before suggesting any tests, the practitioner might look at symptoms, medical history, the medications you are taking, lifestyle factors, and your risk profile. A diagnosis typically consists of blood tests which measure glucose levels either over a period or at a particular point.

What Tests May Be Used to Check for Diabetes?

Common diabetes tests include:

• HbA1c test, which measures average blood glucose levels over approximately three months
• Fasting blood glucose test, which measures glucose levels after fasting
• Oral glucose tolerance test, which checks how your body responds to glucose

How Is Type 2 Diabetes Managed?

The approach is aimed at keeping blood glucose levels healthy and at lowering the chance of complications.

Management might include:

• Balanced eating habits
• Regular physical activity
• Weight management where appropriate
• Blood glucose monitoring
• Medicines when prescribed
• Regular health reviews

Can Type 2 Diabetes Be Prevented or Delayed?

People can reduce their risk of getting type 2 diabetes by making healthy changes to their way of life.

A few helpful steps could include:

• Staying physically active
• Eating a balanced diet with a variety of nutritious foods
• Maintaining a healthy weight
• Avoiding smoking
• Managing blood pressure and cholesterol

When Should You See a GP?

If you do experience serious symptoms such as confusion, extreme weakness, vomiting, or the signs of severe dehydration, you should seek immediate medical advice.

Arrange an appointment if you notice:

• Increased thirst or urination
• Unexplained weight changes
• Ongoing fatigue
• Vision changes
• Tingling or numbness
• Slow-healing wounds

Parkwood Green Medical can recommend consultations by general practitioners to help patients who are worried about diabetes symptoms, risk factors, or blood glucose testing. A medical assessment can then be carried out to determine the appropriate next steps in view of your health needs.
