Understanding Diabetes: Causes, Symptoms, and Treatment

Diabetes is a chronic condition that affects millions of people worldwide. It is a metabolic disorder characterized by high blood sugar levels, either because the body does not produce enough insulin or because cells do not respond to the insulin that is produced.

In this blog post, we will explore the causes, symptoms, and treatment options for diabetes.

What is Diabetes?


Diabetes is a medical condition characterized by high blood sugar levels. This occurs when the pancreas is unable to produce sufficient insulin, or when the body cannot effectively respond to insulin. Insulin is essential as it acts as a key, helping glucose from the bloodstream to reach the cells where it is used for energy.

Diabetes can affect people of any age, and while most forms are chronic, they can be managed through medication and lifestyle modifications.

The primary source of glucose is carbohydrates in our diet. When consumed, these carbohydrates are broken down into glucose, which is transported through the bloodstream to the cells. However, without sufficient insulin, glucose remains in the bloodstream, leading to high blood sugar levels, a condition known as hyperglycemia.

Persistent hyperglycemia can lead to several health complications over time, including heart disease, nerve damage, and eye disorders.

The formal term for diabetes is diabetes mellitus. It’s worth noting that there is another condition with a similar name – diabetes insipidus. Despite sharing the term ‘diabetes’, they are distinct conditions. The common denominator between them is that they both cause increased thirst and frequent urination. However, diabetes insipidus is significantly less common than diabetes mellitus.

What Are The Types of Diabetes?

There are multiple variations of diabetes, including the following:

Type 2 diabetes: In this type, the body either doesn’t produce enough insulin or the body’s cells don’t respond properly to insulin (insulin resistance). This is the most common form of diabetes, primarily affecting adults but can also occur in children.

Prediabetes: This is the stage before Type 2 diabetes, where blood glucose levels are higher than normal but not high enough for an official Type 2 diabetes diagnosis.

Type 1 diabetes: This autoimmune disease occurs when the immune system attacks and destroys insulin-producing cells in the pancreas for unknown reasons. Approximately 10% of people with diabetes have Type 1, which is typically diagnosed in children and young adults but can develop at any age.

Gestational diabetes: This form occurs during pregnancy and usually disappears after childbirth. However, having gestational diabetes increases the risk of developing Type 2 diabetes later in life.

Other types of diabetes include:

Type 3c diabetes: This type occurs when the pancreas is damaged, affecting its ability to produce insulin. Pancreatitis, pancreatic cancer, cystic fibrosis, and hemochromatosis can all lead to this form of diabetes. Removal of the pancreas also results in Type 3c diabetes.

Latent autoimmune diabetes in adults (LADA): Similar to Type 1 diabetes, LADA is an autoimmune reaction but develops more slowly. It is usually diagnosed in individuals over the age of 30.

Maturity-onset diabetes of the young (MODY): MODY, also known as monogenic diabetes, is caused by an inherited genetic mutation that affects insulin production and usage. There are currently over 10 different types of MODY, which affects around 5% of people with diabetes and often runs in families.

Neonatal diabetes: This rare form of diabetes occurs within the first six months of life and is also a type of monogenic diabetes. About 50% of babies with neonatal diabetes have a lifelong form called permanent neonatal diabetes mellitus. For the other half, the condition disappears within a few months but may reappear later in life, known as transient neonatal diabetes mellitus.

Brittle diabetes: This form of Type 1 diabetes is characterized by frequent and severe episodes of high and low blood sugar levels. The instability often requires hospitalization, and in rare cases, a pancreas transplant may be necessary for permanent treatment of brittle diabetes.

How Common is Diabetes?

Diabetes is a prevalent chronic health condition affecting a significant portion of the global population.

According to the International Diabetes Federation (IDF), approximately 463 million adults (20-79 years) were living with diabetes in 2019.

This number is expected to rise to 700 million by 2045 if no substantial preventive measures are taken.

Thus, diabetes is a widespread health concern that requires attention and proactive management strategies.

What Are The Symptoms of Diabetes?

Some of the symptoms associated with diabetes are:

  • Increased thirst and frequent urination
  • Unexplained weight loss
  • Fatigue and weakness
  • Blurred vision
  • Slow healing of cuts and wounds
  • Tingling or numbness in hands and feet
  • Frequent infections, such as gum or skin infections
  • Darkened patches of skin
  • Feeling hungry even after eating
  • Irritability

It is important to note that these symptoms may vary from person to person, and some individuals may not experience any symptoms at all. If you suspect you may have diabetes, it is crucial to consult a healthcare professional for proper diagnosis and treatment.

Furthermore, further information regarding specific symptoms for each type of diabetes are as follows:

Symptoms of type 1 diabetes can develop rapidly within a few weeks or months. In severe cases, there may be additional symptoms indicating a life-threatening complication known as diabetes-related ketoacidosis (DKA). These symptoms include vomiting, stomach pains, fruity-smelling breath, and labored breathing.

Type 2 diabetes and prediabetes may not present any noticeable symptoms or they may develop slowly. High blood sugar levels may be detected through routine bloodwork before symptoms become apparent. Darkened skin on certain areas of the body (acanthosis nigricans) can also be a sign of prediabetes.

Gestational diabetes typically does not show noticeable symptoms. However, healthcare providers will conduct tests for gestational diabetes between the 24th and 28th weeks of pregnancy.

What Causes Diabetes?

Diabetes is caused by excessive glucose in the bloodstream, regardless of the type. However, the reason for high blood glucose levels differs depending on the type of diabetes.

The causes of diabetes include:

Insulin resistance: Type 2 diabetes mainly occurs due to insulin resistance. This happens when cells in the muscles, fat, and liver do not respond properly to insulin. Several factors contribute to varying degrees of insulin resistance, such as obesity, lack of physical activity, diet, hormonal imbalances, genetics, and certain medications.

Autoimmune disease: Type 1 diabetes and LADA occur when the immune system attacks the insulin-producing cells in the pancreas.

Hormonal imbalances: Pregnancy can lead to insulin resistance due to hormones released by the placenta. If the pancreas cannot produce enough insulin to overcome this resistance, gestational diabetes may develop. Other hormone-related conditions like acromegaly and Cushing syndrome can also cause Type 2 diabetes.

Pancreatic damage: Physical damage to the pancreas, caused by a condition, surgery, or injury, can impair its ability to produce insulin, resulting in Type 3c diabetes.

Genetic mutations: Certain genetic mutations can cause MODY and neonatal diabetes.

Long-term use of certain medications, including HIV/AIDS medications and corticosteroids, can also lead to Type 2 diabetes.

In general, the exact cause of diabetes can vary depending on the type and individual circumstances. However, it is typically a combination of genetic, lifestyle, and environmental factors.

What Are The Complications of Diabetes?

Diabetes can result in immediate (sudden and severe) and long-term complications, primarily due to excessively high blood sugar levels that are either extreme or prolonged.

Immediate complications of diabetes

Immediate complications of diabetes that can be life-threatening include:

Hyperosmolar hyperglycemic state (HHS): This complication primarily affects individuals with Type 2 diabetes. It occurs when blood sugar levels remain very high (over 600 milligrams per deciliter or mg/dL) for an extended period, leading to severe dehydration and confusion. Immediate medical treatment is necessary.

Diabetes-related ketoacidosis (DKA): This complication primarily affects individuals with Type 1 diabetes or undiagnosed T1D. It occurs when the body does not have enough insulin. Without insulin, glucose cannot be utilized for energy, so fat is broken down instead. This process eventually releases ketones, which make the blood acidic. Symptoms include labored breathing, vomiting, and loss of consciousness. Immediate medical treatment is required for DKA.

Severe low blood sugar (hypoglycemia): Hypoglycemia occurs when blood sugar levels fall below the healthy range. Severe hypoglycemia indicates very low blood sugar and primarily affects individuals with diabetes who use insulin. Signs include blurred or double vision, clumsiness, disorientation, and seizures. Emergency glucagon treatment and/or medical intervention are necessary.

Long-term complications of diabetes

Prolonged high blood sugar levels can cause damage to the body’s tissues and organs, primarily due to harm to blood vessels and nerves that support bodily tissues.

The most common type of long-term diabetes complication is cardiovascular (heart and blood vessel) issues, which include:

  • Coronary artery disease.
  • Heart attack.
  • Stroke.
  • Atherosclerosis.

Other complications of diabetes include:

  • Nerve damage (neuropathy), which can result in numbness, tingling, and/or pain.
  • Nephropathy, which can lead to kidney failure or necessitate dialysis or transplantation.
  • Retinopathy, which can cause blindness.
  • Foot conditions related to diabetes.
  • Skin infections.
  • Amputations.
  • Sexual dysfunction caused by nerve and blood vessel damage, such as erectile dysfunction or vaginal dryness.
  • Gastroparesis.
  • Hearing loss.
  • Oral health problems, like gum (periodontal) disease.

Living with diabetes can also impact mental health. Individuals with diabetes are two to three times more likely to experience depression than those without diabetes.

How is Diabetes Diagnosed?

Diabetes can be diagnosed through a combination of medical tests and evaluations. The diagnostic process typically involves the following steps:

Medical history: The healthcare provider will review the patient’s medical history, including any symptoms or risk factors associated with diabetes. They will inquire about frequent urination, increased thirst, unexplained weight loss, family history of diabetes, and other related symptoms.

Physical examination: A physical examination may be conducted to look for signs of diabetes, such as high blood pressure, excessive weight, or abdominal obesity.

Blood tests: Blood tests are crucial for diabetes diagnosis. The two primary tests used are:

  • Fasting plasma glucose (FPG) test: This test measures the patient’s blood sugar level after an overnight fast. A result equal to or higher than 126 milligrams per deciliter (mg/dL) on two separate occasions indicates diabetes.
  • Hemoglobin A1c (HbA1c) test: This test measures average blood sugar levels over the past two to three months. An HbA1c level of 6.5% or higher on two separate tests confirms diabetes.

Oral glucose tolerance test (OGTT): The OGTT may be used if the FPG or HbA1c results are inconclusive. It involves measuring blood sugar levels before and two hours after consuming a sugary drink. A blood sugar level of 200 mg/dL or higher after two hours indicates diabetes.

Gestational diabetes screening: Pregnant women may undergo glucose screening between 24 and 28 weeks of pregnancy to check for gestational diabetes. This test involves drinking a sugary solution and measuring blood sugar levels afterwards.

During the diagnostic process, it is important to rule out any potential causes of high blood sugar other than diabetes, such as certain medications or medical conditions. Additionally, repeat testing and follow-up appointments may be required to confirm the diagnosis and determine the appropriate treatment plan.

How is Diabetes Managed?

Diabetes can be managed through various approaches, which typically include lifestyle modifications, medication, and regular monitoring. The specific management plan varies depending on the type of diabetes and the individual’s needs.

Lifestyle Modifications

Healthy Diet: Following a balanced diet that focuses on whole grains, lean proteins, fruits, vegetables, and healthy fats can help manage diabetes. Limiting the intake of sugary and processed foods is crucial.

Regular Exercise: Engaging in physical activity regularly helps control blood sugar levels, improves insulin sensitivity, and promotes overall well-being. A combination of aerobic exercises, strength training, and flexibility exercises is recommended.

Weight Management: Maintaining a healthy weight or losing excess weight is essential for diabetic individuals. Weight management can improve blood sugar control and reduce the risk of complications.

Smoking Cessation: If the individual with diabetes smokes, quitting is highly recommended as smoking can worsen the complications associated with diabetes.


Insulin Therapy: People with type 1 diabetes often require insulin therapy to regulate blood sugar levels. Some individuals with type 2 diabetes may also need insulin if other medications fail to control their blood sugar adequately.

Oral Medications: For type 2 diabetes, various oral medications are available to help manage blood sugar levels. These medications work in different ways, such as stimulating insulin production, reducing glucose production in the liver, or improving insulin sensitivity.

Regular Monitoring

Blood Sugar Monitoring: Regular monitoring of blood sugar levels is crucial to assess the effectiveness of the management plan and make necessary adjustments. This can be done through self-monitoring using a glucose meter or continuous glucose monitoring systems.

Hemoglobin A1c Testing: This test provides an average of blood sugar levels over the past two to three months. It helps evaluate long-term glucose control and adjust the treatment plan if needed.

Blood Pressure and Cholesterol Monitoring: Diabetic individuals are at higher risk of developing high blood pressure and abnormal cholesterol levels. Regular monitoring and appropriate management of these factors are essential to reduce the risk of complications.

Managing diabetes requires a comprehensive approach that combines lifestyle modifications, medication, and regular monitoring. It is crucial for individuals with diabetes to work closely with their healthcare team to develop a personalized management plan that meets their specific needs and goals.

How Can I Prevent Diabetes?

There are several ways to prevent diabetes:

Maintain a healthy weight: One of the most effective ways to prevent diabetes is to maintain a healthy weight. This can be achieved through regular exercise and a balanced diet.

Stay physically active: Engaging in regular physical activity can help prevent diabetes. Aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week.

Eat a balanced diet: Focus on eating a diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit the consumption of processed foods, sugary beverages, and foods high in saturated and trans fats.

Control portion sizes: Be mindful of portion sizes to avoid overeating. Use smaller plates and bowls to help control portion sizes and prevent excessive calorie intake.

Avoid sugary drinks: Sugary beverages like soda, fruit juices, and energy drinks can contribute to weight gain and increase the risk of diabetes. Opt for water, unsweetened tea, or infused water as healthier alternatives.

Limit alcohol consumption: Excessive alcohol intake can lead to weight gain and increase the risk of diabetes. If you choose to drink alcohol, do so in moderation (up to one drink per day for women and up to two drinks per day for men).

Quit smoking: Smoking increases the risk of diabetes and other health conditions. Quitting smoking can significantly reduce the risk of developing diabetes.

Get regular check-ups: Regular check-ups with your healthcare provider can help identify any early signs or risk factors for diabetes. They can provide guidance on how to prevent diabetes and manage any existing conditions effectively.

Remember, prevention is key when it comes to diabetes. By adopting a healthy lifestyle and making smart choices, you can significantly reduce your risk of developing this chronic condition.

What is The Prognosis for Diabetes?

The prognosis for diabetes can vary significantly depending on various factors, such as the type of diabetes, the management of the condition over time, access to diabetes care, age at diagnosis, duration of diabetes, presence of other health conditions, and development of complications.

Chronic high blood sugar can lead to irreversible complications, which have been proven to shorten lifespan and diminish quality of life if left untreated.

Diabetes is the eighth leading cause of death in the United States, with many individuals dying from heart attacks or strokes. However, it is important to recognize that a healthy life is attainable with diabetes.

Lifestyle changes, regular exercise, dietary adjustments, and consistent blood sugar monitoring are essential for a better prognosis.

Studies indicate that maintaining A1c levels below 7% may help reduce the risk of complications in individuals with diabetes.

When Should I Consult My Healthcare Provider?

If you are not yet diagnosed with diabetes, it is advisable to consult a healthcare provider if you experience any symptoms of diabetes, such as increased thirst and frequent urination.

If you already have diabetes, it is important to regularly see your healthcare provider who assists in managing your diabetes, such as an endocrinologist.
