Introduction

Purpose of the food we eat is to provide nutrition and energy to the body. But Diabetes Mellitus is a condition wherein your body can't absorb or use the energy produced after consuming food. The diabetes mellitus symptoms are shown in human beings in only two terms as mentioned below:

  1. The pancreas produces naturally occurring hormones like insulin which helps convert sugar for energy. In the case of diabetes mellitus, the pancreas creates nominal or no insulin. 

  2. In other cases, the insulin produced by the pancreas doesn't function normally.

 

About Diabetes Mellitus

To put simply, it is a disorder wherein someone’s body fails to produce sufficient insulin from pancreas or fails to make use of it to produce energy. As a result, your body has a high level of blood sugar which leaves adverse effects on your health. It is also considered a life-threatening disease and may cause other issues in the human body. 

Primarily, these are divided into two classes, as shown below. 

Types of Diabetes Mellitus


Type 1 Diabetes 

Type 2 Diabetes 

In this kind, beta cells of pancreas are damaged and fail to produce insulin hormone. 

Here, pancreas produces insulin; however, they aren’t sufficient to fulfil the need of body. 

This isn’t as common as type 2. However, it is mostly seen in individuals less than 30 years of age. 

Most people show type 2 diabetes mellitus symptoms. It occurs mostly in individuals more than 40 years of age but can also happen to children.                                 

In this case, the patient needs to use insulin injections for protection against it. 

It is possible to control type 2 diabetes by adopting a healthy diet, exerciser routine, and weight management training, medications, or injections. 


Besides these two, there can be several other kinds of diabetes mellitus caused by surgery, use of medicines, other illnesses, and conditions. One such type is Gestational diabetes which occurs in case a pregnant woman with no history of diabetes starts showing this symptom. Therefore, pregnant women over the age of 35, having a family history of diabetes, or overweight individuals have a high chance of developing dm symptoms. 


Main Symptoms of Diabetes

Most common symptoms shown by diabetes mellitus patients are listed below. 

  • Feeling hungry even after eating. 

  • Increased feeling of thirst. 

  • Frequent urination. 

  • Fatigue. 

  • Weight loss. 

  • Healing a wound or cut takes time. 

  • Blurred vision. 

  • Urine or yeast infections. 

  • Dry & itchy skin. 


These are a few diabetes mellitus type 2 symptoms which a patient may show in case their body stops creating insulin or doesn't produce sufficient insulin. In either case, the patient needs to seek immediate medical attention so that their health can recover. 

Test Your Knowledge 

1. Choose the Appropriate Risk Factor Concerning Type 2 Diabetes Mellitus.

  1. Dietary fat intake in a considerable amount 

  2. Overweight 

  3. Family history with diabetes 

  4. All of the above 


2. Choose the most Suitable Option which Distinguishes Between Type 2 and Type 1 Diabetes. 

  1. Patients having type 1 diabetes can quickly develop chronic disorders. 

  2. Oral hypoglycemic agents can be taken to increase endogenous insulin production in type 1 diabetes patients. 

  3. Type 2 diabetes patients need a lower dose of insulin compared to the ones with type 1 because it's a milder type. 

  4. In the case of type 1 pathogenesis, autoimmune factors are present, which isn't the case with type 2.

 

Treatment for Diabetes Mellitus 

  • Time to time diagnosis of blood sugar levels. 

  • Having a diet plan according to your blood sugar level. 

  • Regular exercise. 

  • Medications and injections as recommended by physicians. 


Therefore, it is possible to control the blood sugar levels of a patient by undergoing the right kind of treatment. Now that you have learnt the clinical features of diabetes mellitus, you will be able to answer even tricky questions quickly.

Risk Factors of Diabetes

The factors that raise your risk vary depending on the kind of diabetes you eventually acquire are:

  • Having a Type 1 diabetes family history either to your parents or siblings.

  • Autoantibodies are present in your system. Autoantibodies are antibodies that erroneously target the tissues or organs of your own body.

  • Any type of physical stress such as illness or surgery.

  • Exposure to viruses-caused diseases.


The Following are Some of the Risk Factors For Prediabetes and Type 2 Diabetes:

  • A family history of prediabetes or Type 2 diabetes.

  • Being Overweight.

  • High Blood Pressure

  • Physically Inactive

  • Having a low HDL cholesterol level and a high triglyceride level.

  • Having a family history of cardiovascular disease or heart stroke.

  • Having gestational diabetes or having a baby that weighs more than 9 pounds.


Risk Factors For Gestational Diabetes Include:

  • The Family history of prediabetes or Type 2 diabetes.

  • Being overweight before your pregnancy.

  • Being over 25 years of age.


What causes Diabetes?

Diabetes, irrespective of type, is caused by having too much glucose circulating in your blood. The cause of your increased blood glucose levels differs depending on the kind of diabetes you have:

Type 1 Diabetes - This is a disease of the immune system. Insulin-producing cells in your pancreas are attacked and destroyed by your body. If you don't have enough insulin to let glucose into your cells, it builds up in your bloodstream. Genes may also have a role in some cases. A virus can also cause an immune system attack.


Type 2 and Prediabetes - Insulin does not function properly in your body's cells, preventing glucose from entering them. Insulin resistance has formed in the cells of your body. Your pancreas can't keep up with insulin requirements and can't produce enough to overcome the resistance. Glucose levels in the bloodstream grow.


Gestational Diabetes - During pregnancy, hormones generated by the placenta make your body's cells more resistant to insulin. Your pancreas is unable to make sufficient insulin to overcome this resistance. There is an excessive amount of glucose in your bloodstream.


How is Diabetes Managed and Treated?

Diabetes affects every part of your body. You'll need to take steps to keep your risk factors under control and within normal ranges if you want to properly manage diabetes, such as:

  • Following a healthy meal plan. Follow a Mediterranean or Dash diet, which includes vegetables, whole grains, fruits, and healthy fats. These diets are high in fibre and nutrients, yet low in fats and calories. Consult a professional nutritionist for help with nutrition and meal planning.

  • On most days of the week, try to exercise for at least 30 minutes. Take a walk, swim, or engage in another activity or sport that you like.

  • If you are overweight, you must lose weight. Develop a weight-loss strategy with the help of an expert.

  • Taking medicine and insulin as recommended and according to the instructions on how and when to take them.

  • Keep track of your blood sugar and blood pressure at home.

  • Maintaining regular contact with your doctor and completing laboratory testing as directed by your doctor.

FAQs on Diabetes Mellitus

1. What Causes Diabetes Mellitus? 

Diabetes mellitus is a metabolic disease caused by insufficiency of insulin in the body. In this condition, either your body doesn't create insulin or doesn't produce sufficient insulin for normal functioning.  

2. How can Diabetes Mellitus have a Massive Impact on the Immune System? 

Besides affecting the metabolic system, the disorder also has a significant impact on other parts of the body, such as the nervous system, heart, kidney, etc. Therefore, it has the potential to affect the immune system. 

3. What are Diabetes Mellitus Symptoms? 

Fatigue, increasing hunger or thirst, frequent urination, blurred vision, weight loss, etc. is a few symptoms that patients with diabetes mellitus show. 

4. How does the glucose level in the blood gets high?

Digestion is the process of breaking down the food you consume into numerous nutritional sources. When you eat carbs, your body converts them into sugar/glucose. When glucose enters your bloodstream, it requires assistance – a "key" – to reach its last destination, which is inside your body's cells. Insulin is the "help" or "key" to this. Insulin is a hormone produced by the pancreas, which is positioned below the stomach. Your pancreas secretes insulin into your bloodstream. Insulin functions as the "key" that unlocks the cell wall "door," allowing glucose to enter the cells of your body. Glucose supplies the energy that tissues and organs require to function effectively. If a person has diabetes:

  • Their pancreas produces no or insufficient insulin.

  • Their pancreas produces insulin, but the body's cells do not respond to it and cannot utilise it as they should.

If glucose is unable to reach your body's cells, it remains in your bloodstream, increasing your blood glucose level.
