Understanding Diabetes Mellitus: Causes, Types, and Treatments

Understanding Diabetes Mellitus: Causes, Types, and Treatments Have you ever wondered why some people are diagnosed with Diabetes Mellitus (DM) while others are not? Have you ever desired to know more about the different types of DM and how the treatment? If so, you’ve come to the right spot.

In this article, we’ll look at what DM is and the various types of it. We’ll also explore some of the potential causes and discuss possible treatments. With the proper understanding, you’ll be well-equipped to manage this condition better or help a loved one cope effectively. So let’s get started!

What Is Diabetes Mellitus?

If you’ve heard of diabetes, you know it’s a disorder of how our bodies process glucose, a type of sugar we use for energy. But what is diabetes mellitus (DM) specifically?

DM is a chronic disease that attacks the body’s ability to regulate the amount of sugar in the blood. It occurs when your pancreas doesn’t produce enough insulin—a hormone that helps move glucose into cells—or when your cells don’t respond typically to insulin. As a result, too much sugar (glucose) accumulates in the bloodstream, leading to serious health problems like heart disease, vision loss, nerve damage, and kidney damage.

DM into five types: type 1, type 2, maturity-onset diabetes of the young (MODY), gestational diabetes, and neonatal diabetes. Each class has distinct characteristics and requires different treatment strategies. In addition, steroid-induced diabetes can also occur due to taking corticosteroids or other glucocorticoid hormones for an extended period.

The Different Types of Diabetes Mellitus

Understanding Diabetes Mellitus: Causes, Types, and Treatments

When it comes to diabetes mellitus, there are several types—each with its unique causes, symptoms, and treatments. Here’s a quick overview of the most common types of DM:

Type 1 – diabetes is an autoimmune condition effect by destroying insulin-producing beta cells in the pancreas. It typically affects children, young adults, and adolescents. Treatment is forming on insulin replacement via injections or pumps.

Type 2 – The most common type of diabetes is typical causes by genetics and lifestyle factors, such as being overweight or inactive. The body doesn’t produce enough insulin or use it efficiently. Treatment is formed on medication, diet changes, physical activity, and weight reduction to keep glucose levels under control.

Gestational Diabetes develops during pregnancy due to hormonal changes that affect how the body metabolizes glucose from food. Treatment includes dietary changes, a regular exercise regimen, and possibly oral antidiabetic medications.

Other less common forms include neonatal diabetes, congenital diabetes, steroid-induced diabetes, and latent autoimmune diabetes in adults (LADA). It’s essential to understand what kind of DM you have to receive the proper care for your case.

– Type 1 Diabetes Mellitus: An Autoimmune Disease

You might not know that Type 1 Diabetes Mellitus (T1DM) is an autoimmune disease. It means that your body’s immune system is mistakenly attacking cells in your pancreas, which are responsible for producing insulin—the hormone our bodies need to convert sugar into energy.

It isn’t your body’s choice, and some variables affect the likelihood of developing T1DM. For instance, a genetic component—a family history of T1DM increases the chances of developing it compared to those without a family history. In addition, youngsters with early onset may have virus-induced diabetes; however, this theory is still controversial.

Risk factors for Type 1 Diabetes Mellitus

People with certain traits have a greater risk of developing Type 1 Diabetes Mellitus than others:

  • Infants younger than age 6 months
  • Positive antibodies present in the blood (indicating an immune system condition)
  • Being white or of European descent
  • Having a family history of T1DM

With its autoimmune origins, T1DM is irreversible; however, treatments are available to manage its symptoms and medical effects.

– Type 2 Diabetes Mellitus: Lifestyle and Genetics

When it comes to Type 2 Diabetes Mellitus, both lifestyle and genetics play an essential role. This type of DM is usually seen in adults and is closely associated with poor lifestyle habits, such as not eating a balanced diet and getting enough physical activity. It can also result from a family history of diabetes—if a close family member has diabetes, your chances of having Type 2 DM can double or even triple.


Your genes are essential in determining your risk for developing Type 2 DM. Specific populations may be more likely to develop this type of diabetes than others due to differences in gene variants that increase the risk for Type 2 DM. For example, African Americans are known to be at an increased risk for developing this condition because they have higher rates of specific genetic variations that can lead to insulin resistance.


The main lifestyle factor associated with developing Type 2 DM is obesity due to poor food choices and lack of physical activity. When you consume too many calories and don’t exercise regularly, your body becomes resistant to insulin. In addition, when the body doesn’t respond appropriately to insulin signals, glucose levels become higher than average. A warning sign that you may need to make some replacements to lower your risk for disease development or progression.

– Maturity-Onset Diabetes of the Young (MODY)

Another type of diabetes worth mentioning is Maturity-Onset Diabetes of the Young (MODY). It’s a rare form of diabetes that typically starts in adolescence or early adulthood, and genetic mutations cause it. An estimated one percent of all people diagnosed with diabetes have MODY.

It behooves those diagnosed with MODY to take special care as the condition can vary significantly, even within members of the same family. That means test results are monitored and closely followed from generation to generation.

The causes of MODY include:

  1. Chromosomal mutations in specific genes
  2. Mutations in mitochondrial DNA (mtDNA)
  3. Autosomal dominant mutations
  4. Autosomal recessive mutations
  5. Multifactorial inheritance
  6. Impaired insulin secretion from beta cells
  7. Deficient insulin action by target cells

In general, MODY is treated differently than other types of diabetes and may require more specialized treatment options for each patient instead of a “one-size-fits-all” approach to therapy and management.

– Gestational Diabetes Mellitus: Diabetes During Pregnancy

Gestational diabetes, diabetes during pregnancy, is also a type of diabetes. It can happen when the mother’s pancreas is not producing enough insulin to handle the additional glucose her body is making for her baby. Women predisposed to developing gestational diabetes diagnoses at their first prenatal visit.


Excess weight gain during pregnancy, a family history of diabetes, age over 25, and being African American, Hispanic-American. Native American, or Asian-American can put you at risk for gestational diabetes. However, even if none of these factors applies to you, it’s still important to get tested for gestational diabetes early in your pregnancy.


Most women with gestational diabetes can keep it under control with diet and exercise alone. However, an essential part of controlling the condition is monitoring your blood sugar levels and keeping them within a healthy range to ensure you stay off any required medication. It’s also best to attend all prenatal visits so your doctor can monitor your progress throughout your pregnancy and adjust any treatments as needed.

– Neonatal Diabetes Mellitus: Diabetes in Infants

Have you heard of neonatal diabetes mellitus? It’s a type of diabetes that affects newborns, and you might be surprised to learn that 2-3% of all infants with diabetes have this form.

Symptoms at Birth

Neonatal diabetes can appear at birth but is often not diagnosed until the baby is 4-6 months old. Signs may include increased thirst and urination, poor feeding, and dehydration. When those symptoms arise, it’s essential to have the baby tested for diabetes right away.

Potential Causes of Neonatal Diabetes

Experts are still trying to determine why neonatal diabetes occurs. Still, some potential causes include inherited genetic mutations from either or both parents and environmental triggers like viruses or other toxins.

Currently, there are two known approaches for treating neonatal diabetes:

  1. Insulin injections – if diagnosed early enough in development
  2. Switching from insulin to oral medication – typically taking place in childhood

Understanding Diabetes Mellitus- Steroid-Induced Diabetes Mellitus: Caused by Medications

Understanding Diabetes Mellitus: Causes, Types, and Treatments

When it comes to steroid-induced diabetes mellitus, you might not know what this is either. That’s okay: it has to do with medications. If you take drugs like prednisone or other corticosteroids for an extended period, you could be at risk for developing steroid-induced diabetes.

That’s because these medications can interfere with the body’s ability to produce enough insulin and use it efficiently, resulting in higher blood glucose levels. In some cases, this type of diabetes can go away once the steroid treatment end.

However, if you’ve been taking medications for a long time, your doctor may want to monitor your blood sugar levels and check for signs of diabetes due to long-term use. It might also be necessary for them to adjust your medication dosage or switch prescriptions if necessary. All to keep your blood glucose levels regular and avoid diabetes complications down the road.

Diagnosing Diabetes Mellitus: Blood Tests and Screening

Diagnosis of diabetes mellitus is not tricky, but it does require several blood tests and screenings. Typically, your doctor will ask you to do a fasting glucose test or an oral glucose tolerance test. With a fasting glucose test, your doctor will take a blood sample and measure the amount of glucose in it after you have fasted for at least 8 hours. An oral glucose tolerance test requires that you fast overnight and drink a sugary drink in the morning, after which they will measure your blood sugar levels at intervals over two hours to see how it responds to the sugary drink.

The American Diabetes Association (ADA) recommends testing for prediabetes if any of these conditions are true for you:

  • You are 45 years old or older
  • Your waist size is more than 35 inches if you are female or 40 inches male.

Additionally, they recommend that everyone cross-examine every 3 years starting at age 45 (or sooner if there is any suspicion of diabetes). As well as to these tests other tests may include hemoglobin A1c (HbA1c), random plasma glucose, or urine tests. Suppose any of these tests come back positive. In that case, your doctor may also order additional tests, such as an A1C blood test or a Glycohemoglobin Test, to confirm the diagnosis of diabetes mellitus.

Complications and Health Risks of Uncontrolled Diabetes

Having uncontrolled diabetes means living with an increased risk of other health problems. Some of those risks are heart disease, blindness, kidney failure, and the need to amputate limbs due to circulation issues. And while it sounds scary, you should know that it’s all preventable with proper medical care.

The best way to keep away from these complications is by making sure that you get regular check-ups and keep your blood sugar levels in check. It’s also important to follow any lifestyle changes prescribed by your doctor—such as eating healthy and exercising regularly—to help maintain good health.

Though complications start at different times in different people, here are some of the more common ones seen in those with uncontrolled diabetes:

  1. High Blood Pressure: Long-term high blood pressure can lead to heart attacks, strokes, eye damage, and kidney damage.
  2. Neuropathy: Damage to nerves from diabetes can lead to pain or loss of feeling in the arms, legs, hands, and feet, which can become infected or result in amputations if not treated quickly.
  3. Vascular Disease: An accumulation of cholesterol on the walls of arteries can cause a blockage and reduce blood flow, increasing the risk of heart attack or stroke.
  4. Damage to Kidneys: Diabetes increases the risk for chronic kidney diseases because high sugar levels over time weaken filtering membranes within the kidneys resulting in fluid retention and elevated blood pressure levels. Which makes them prone to other conditions such as cancer.
  5. Eye Damage: Diabetes is one of the leading causes of blindness because it affects the eyes’ ability to focus correctly, resulting in vision loss if left untreated for too long.

Treatment Options for Diabetes Mellitus

When treating diabetes mellitus, many options can help you manage diabetes and reduce the risk of long-term complications. First, hang on to the type of diabetes you have; treatments usually involve monitoring blood sugar levels, medication. Lifestyle changes such as eating a healthy diet and exercising regularly, and possibly insulin injections.

The treatment goals for diabetes mellitus include achieving normal or near-normal blood sugar levels and ensuring that your blood sugar stays stable. In addition, it may be necessary to adjust your medications depending on the type of diabetes you have.

Here are some possible treatment options for managing diabetes:

  1. Oral medications such as metformin to help control blood sugar levels
  2. Insulin injections to help maintain blood sugar levels if oral medications fail
  3. The healthy way of life changes like eating a balanced diet and exercising regularly
  4. Weight loss, if needed
  5. Regular monitoring of your blood sugar levels to make sure they remain within a normal range
  6. Regular visits to healthcare professionals for monitoring and evaluation

– Insulin Injections for Understanding Diabetes Mellitus

If you have diabetes, chances are you’ve heard of insulin injections. Insulin injections are a standard treatment for those with type 1, 2, or MODY diabetes. The process is relatively simple—injecting insulin into your body through a pre-filled syringe or pen device.

So why is insulin used to treat diabetes?

It helps regulate blood glucose levels.

Insulin acts on the liver cells to block the release of glucose into the bloodstream. It means it helps regulate blood glucose levels, ensuring they don’t go too high (hyperglycemia) or too low (hypoglycemia).

It can help delay or prevent complications related to diabetes

Insulin can help you manage your condition and control its various associated aspects. Protection of your blood sugar levels in check and insulin injections can also help reduce your risk of complications like kidney failure and cardiovascular disease.

It’s important to note that insulin injections drown as prescribed by your doctor and that the timing of injection follows as closely as possible. It’s also important to remember that insulin injections must consistently finish with a healthy lifestyle, such as exercising regularly and following a balanced diet.

Lifestyle Changes for Understanding Diabetes Mellitus

Even if you get an official diagnosis of diabetes, that’s no reason to panic. There are a lot of pace you can take to manage your condition, even without taking medications.

And when it comes to lifestyle changes, you should first talk to your doctor about what kind of physical activity would be best for you. Regular exercise helps reduce blood sugar levels, as well as improving levels of cholesterol and blood pressure. Plus, it also really helps with weight loss and maintenance.

Diet Changes for Understanding Diabetes Mellitus

Your diet can make a difference in controlling your diabetes too. For example, switching out refined sugar for whole grain products and reducing your intake of saturated fats can positively affect your health. Also, eating more fruits and vegetables can help reduce your risk for diabetic complications like heart attack, stroke, and kidney disease.

Stress Management for Understanding Diabetes Mellitus

Stress is also a potential trigger for diabetes-related health issues, so finding healthy ways to manage stress levels is essential. It can include practicing yoga or mindfulness meditation or even taking short walks throughout the day. The key is finding something that works for you!

Living With Diabetes: Diet, Exercise and Glucose Monitoring

If you have diabetes, you know it requires a lot of active management. You must ensure your diet is healthy, exercise, and monitor your glucose levels to prevent hyperglycemia (high blood sugar) or hypoglycemia (low blood sugar).

Diet for Understanding Diabetes Mellitus

Having diabetes doesn’t mean giving up the foods you love. It simply means learning how to manage them in a way that supports your health. Eating healthy foods in smaller amounts and combining meals with physical activity can help keep your blood sugar under control.

Exercise for Understanding Diabetes Mellitus

Getting regular physical activity is another essential part of managing diabetes. Aim for 30 to 60 minutes a day —all at once or broken up into smaller periods of 10 to 15 minutes — of moderate exercises such as fast walking or swimming.

Glucose monitoring Understanding Diabetes Mellitus

When controlling diabetes and preventing serious complications, checking blood sugar levels is critical. Whether you use a finger stick glucometer or a continuous glucose monitoring device, make sure that you check your blood glucose levels regularly. As it helps provide insight into how lifestyle factors affect them.


It’s worth noting that with any diabetes, lifestyle changes, such as being more active and eating a nutritious diet, can profoundly impact the success of your treatment. For example, some people with type 2 DM can increase their insulin sensitivity and reduce their blood sugar levels by making lifestyle changes.

The good news is that diabetes manages, but the key is to be aware of the signs of diabetes and to get early treatment. Then, with the right lifestyle changes and proper management, diabetes managed, and you can live a long and healthy life.
