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.

Polycystic Ovary Syndrome, which is generally known as PCOS, is a hormonal disorder that influences a large number of women throughout their reproductive years and causes changes in the way the ovaries function together with alterations in hormone levels, ovulation patterns, and metabolism.
If you find that your periods are changing continuously, or that you are experiencing new hair growth, acne, or other symptoms associated with hormonal changes, it is advisable to talk to your general practitioner so that your concerns can be evaluated and it can be decided whether further investigation is necessary.

What Is Polycystic Ovary Syndrome (PCOS)?

PCOS is a disorder linked to an imbalance of hormones and to changes in ovarian function. In many cases women who have PCOS exhibit higher levels of androgens, since these are hormones that play a role in reproductive development and other bodily functions.
The term PCOS refers to the presence of numerous small follicles, which may be observed on the ovaries when an ultrasound is performed. It is not the case that all individuals with PCOS show this feature, and the presence of ovarian cysts does not always indicate that someone has PCOS.

What Are the Common Symptoms of PCOS?

The symptoms of PCOS usually develop gradually and differ from person to person. Typical signs are:

• Irregular or Absent Periods
For some women with PCOS the intervals between their periods may be longer, their bleeding may be irregular, or they may have fewer periods than would be expected. Such changes generally occur since hormonal imbalance interferes with ovulation.

• Excess Hair Growth
In some women who have PCOS the level of androgens is higher, which causes hair growth on areas such as the face, chest, abdomen or back.

• Acne or Oily Skin
The hormonal changes associated with PCOS may lead to greater oil production in the skin. Several women observe persistent acne, oily skin, or alterations in skin texture, especially in the area around the jawline, on the face, chest, or back.

• Weight Changes
Women who have PCOS may find it difficult to manage their weight or may observe a gain in weight around their abdomen. Insulin resistance is common in women with PCOS and has an impact on the way the body handles glucose.

• Hair Thinning
The hormonal changes associated with PCOS may lead to hair becoming thinner on the scalp. Hair thinning is often associated with a pattern that relates to androgen sensitivity, and other possible causes such as thyroid disorders, nutritional deficiencies, stress, and other hormonal changes should also be considered.

• Difficulty Conceiving
PCOS is one of the common reasons for ovulation problems, a condition which can sometimes influence fertility. If ovulation does not take place on a regular basis, it may take longer to become pregnant. Many people suffering from PCOS can achieve pregnancy with the right medical support and fertility care.

What Causes PCOS?

It is not entirely known what causes PCOS. Genetic and hormonal factors together play a role in its development. Insulin resistance, higher androgen levels, and alterations in ovarian function are all often found in individuals with PCOS.

Can PCOS Symptoms Vary Between Women?

One person might mainly experience irregular periods, while another might notice acne, excess hair growth, weight changes, or fertility concerns.
Symptoms also change over time. Some women first notice issues during adolescence, while others receive a diagnosis later when fertility or menstrual concerns arise.

How Is PCOS Diagnosed?

No single test diagnoses PCOS. A GP considers your symptoms, medical history, examination findings, and test results together.
• Medical History
During your appointment, the consulting GP might ask about:
• Your menstrual cycle pattern
• Changes in weight
• Skin and hair changes
• Pregnancy history
• Medicines
• Family history of hormonal conditions or diabetes

• Physical Examination
The doctor might check signs related to hormonal changes, including skin changes, hair growth patterns, weight, blood pressure, and other health indicators.
• Blood Tests
Blood tests help assess hormone levels and check for other conditions with similar symptoms.
• Ultrasound When Appropriate
An ultrasound can sometimes be used to examine the ovaries and uterus, and the results contribute to the general evaluation rather than serving as the sole means of diagnosis.

Can PCOS Be Managed?

There is no single method of treating PCOS. The way you are managed will depend on your symptoms, your health objectives, and whether you are planning to have a pregnancy.
Support might include:
• Lifestyle changes to support metabolic health
• Medicines to regulate periods or manage symptoms
• Treatments for acne or excess hair growth
• Fertility support when required
• Regular health monitoring

When Should You See a GP About Possible PCOS?

It’s advisable to seek consultation if you experience:
• Irregular or missed periods
• New facial or body hair growth
• Persistent acne
• Unexplained weight changes
• Hair thinning
• Difficulty becoming pregnant
See that you have an early assessment since it enables the cause of your symptoms to be identified and helps to ensure that you receive appropriate care.

PCOS and Fertility: What Should You Know?

For some women PCOS affects ovulation and this may make it more difficult to get pregnant. Fertility results will differ according to age, ovulation patterns, general health and other factors.
Parkwood Green Medical can help with general practice consultations to women who are experiencing possible signs of PCOS, changes in their menstruation, concerns about their hormones, or questions regarding their fertility.
