Type 1 Diabetes: From Cause to Treatment

About

Type 1 Diabetes Definition

Type 1 diabetes is a health condition where the body's defense system mistakenly attacks cells in the pancreas. These cells are vital for making insulin, a hormone that helps control our blood sugar levels.

Also Known as Juvenile Diabetes

, Type 1 Diabetes predominantly affects children and teenagers aged 4 to 14. However, it's essential to note that this condition can manifest at any age, not just during childhood.

Why Does it Occur?

Insulin, a vital hormone, is produced by the cells in the pancreas. These cells play a pivotal role in regulating insulin secretion. In the case of Type 1 Diabetes, the immune system erroneously identifies the pancreatic beta cells as foreign invaders and launches an autoimmune attack, leading to their destruction.

The consequence is an insufficient or complete absence of insulin production, causing glucose to accumulate in the bloodstream. This elevation in blood sugar levels is the hallmark of diabetes(1^✔ ✔Trusted Source

Did you Know?

Intriguingly, adults over the age of 30 sometimes develop a variant of Type 1 Diabetes known as Latent Autoimmune Diabetes in Adults (LADA). Unlike classic Type 1 Diabetes, LADA progresses more slowly. Additionally, statistics indicate a notable rise in the incidence of Type 1 Diabetes among children, with the prevalence increasing from 1.48 to 2.32 per 1000 between 2002 and 2013(2^✔ ✔Trusted Source

Cause of Type I Diabetes

Type 1 Diabetes is a disease. In this disease, the body's immune system attacks and destroys beta cells. This attack leads to a lack of insulin production leading to excessive glucose in the body causing diabetes.

Some research suggests that the insulin itself is sometimes responsible for triggering this autoimmune response. Certain viral infections may also trigger T1D. When a virus enters the body, T cells make antibodies to fight the virus and its infection.

But sometimes, the antigens in the virus are similar to the beta cells. This causes the T cells to turn against the beta cells destroying it and hampering the production of insulin. Some viruses, like coxsackie, rotavirus, rubella, and enterovirus, attack the intestines and cause mumps(3^✔ ✔Trusted Source

Genetics of Type 1 Diabetes

Heredity: It plays an important role in determining who is likely to develop T1D. Children are more likely to inherit the disease from a father with the disorder than from the mother. However, most people who develop the disease have no family history. Genes carry instructions to make proteins for normal body functions.

The interaction among genes makes an individual susceptible or protects them against the disease. In certain populations, the genetic coding is such that they fail to develop type 1 diabetes.

Autoimmune diabetes mellitus (Type 1A) is a form of diabetes characterized by the immune system mistakenly attacking and destroying insulin-producing beta cells in the pancreas. This autoimmune process leads to an absolute insulin deficiency, requiring individuals to rely on external insulin administration for glucose regulation.

In individuals with a favorable predisposition to type 1 diabetes, gene variants carry instructions for making a protein called Human leukocyte antigen (HLA) in the white blood cells, triggering the body's immune response. The HLA complexes are on chromosome 6, where certain variants contribute to disease development, while others provide protection(4^✔ ✔Trusted Source

Vitamin D deficiency and T1D: There is a belief that supplementing pregnant women and infants prevents T1D. Vitamin D helps the immune system by enhancing insulin sensitivity and controlling blood sugar, binding to receptors in immune cells to prevent the attack on and destruction of beta cells by T cells.

Since the research is inconclusive, a firm link between the two cannot be established.

Type 1 Diabetes Risk Factors

Exposure to Cow’s Milk or Infant Formula

: It may increase the risk of developing type 1 diabetes in infants. Cow’s milk contains a protein that is similar to a protein called glycodelin which controls T cell production. The baby’s body tends to attack the foreign protein from cow’s milk and also attacks glycodelin in the process. This results in an overproduction of T cells which eventually destroy the beta cells responsible for producing insulin (5^✔ ✔Trusted Source

Stress

: It is the body and mind's reaction to things that happen, whether they are good or bad. In the 17th century, people attributed the onset of diabetes to 'prolonged sorrow.' Stress levels in one’s life could be because of family problems, work-related problems or any other issues. Research has found that stress impacts how effectively individuals with diabetes manage their metabolism, further supporting this connection.

Stress, overeating, lack of exercise, alcoholism, and smoking contribute to increased belly fat. This excess belly fat makes it more difficult to manage diabetes and leads to various diabetes-related issues.

This, in turn, evokes a negative response and the vicious cycle continues. Stress causes changes in hormones that affect insulin and sex hormones. It increases cortisol (a stress hormone) and decreases sex steroids(6^✔ ✔Trusted Source

Pollution

: Limited studies have also linked pollutants to type 1 diabetes. Pollutants alter the humoral and cellular immune response. Air pollutants, such as ozone, sulfates, and chemicals from cigarette smoke, can speed up the destruction of beta cells, causing diabetes.

These substances create harmful molecules. These molecules damage cells or increase the presence of diabetes-causing substances. This leads to an immune system reaction.

Some studies have also shown the prevalence of diabetes in areas with more toxic discharge. However, these studies are inconclusive due to their limitations and the nature of bias (7^✔ ✔Trusted Source

Understanding Type 1 Diabetes Symptoms

T1D produces symptoms that are more or less interlinked with each other. Insulin is necessary for converting glucose into energy for the cells. Without insulin, glucose accumulates in the blood, leading to high blood sugar levels.

The body eliminates excess sugar by increasing the frequency of urination. This process leads to the loss of a significant amount of water through urine, causing dehydration and excessive thirst. Additionally, the expulsion of sugar and calories through urine results in weight loss and exhaustion.

Insulin Dependent Diabetes Symptoms:

Recognizing symptoms of insulin-dependent diabetes is vital for timely intervention. Increased thirst, frequent urination, unexplained weight loss, fatigue, and blurred vision are common indicators that may warrant further medical evaluation(8^✔ ✔Trusted Source

Early Signs of Type 1 Diabetes

Being aware of early signs is crucial for the prompt diagnosis and management of type 1 diabetes. Look out for symptoms like increased thirst, frequent urination, sudden weight loss, fatigue, and vision changes, and consult a healthcare professional if these signs arise.

Type 1 Diabetes in Children

Diagnosing and managing type 1 diabetes in children requires special attention. Recognizing symptoms early, coordinating with healthcare professionals, and implementing age-appropriate treatment plans are crucial for effective care.

Type 1 Diabetes in Adults

While commonly associated with children, type 1 diabetes can also develop in adults. Understanding the distinct challenges and symptoms in adults, alongside tailored treatment approaches, is essential for comprehensive diabetes management.

Type 1 Diabetes Diagnosis

Diagnosing type 1 diabetes involves a comprehensive evaluation by healthcare professionals. Key steps in the type 1 diabetes diagnosis process typically include assessing symptoms such as increased thirst, frequent urination, unexplained weight loss, and fatigue. Blood tests, specifically measuring blood glucose levels and sometimes additional auto-antibody tests, play a crucial role in confirming the diagnosis.

Early detection is essential for timely intervention and the development of a personalized management plan for individuals diagnosed with type 1 diabetes. If you suspect symptoms or have concerns, it is advisable to consult with a healthcare professional for a thorough evaluation.

A Guide on Types of Insulin for People with Diabetes

Type	Onset (length of time before insulin reaches bloodstream)	Peak (time period when insulin is most effective)	Duration (how long insulin works for)
Rapid-acting	10 - 30 minutes	30 minutes - 3 hours	3 - 5 hours
Short-acting	30 minutes - 1 hour	2 - 5 hours	Up to 12 hours
Intermediate-acting	1.5 - 4 hours	4 - 12 hours	Up to 24 hours
Long-acting	0.8 - 4 hours	Minimal peak	Up to 24 hours

People should adjust the level of insulin intake according to their diet, exercise, health, and travel.

Adjustments to insulin should be made according to specific requirements. People with diabetes tend to suffer from anxiety and depression which may alter their blood sugar level by causing the release of glucose into the bloodstream(9^✔ ✔Trusted Source

Type 1 Diabetes Treatment

Effective treatment for type 1 diabetes involves insulin therapy, careful monitoring of blood sugar levels, and lifestyle adjustments. Collaborate with healthcare professionals to tailor a treatment plan that addresses your specific needs and optimizes overall well-being.

Living with Diabetes: Management

Here are some simple ways to manage Type 1 Diabetes Mellitus:

Balanced Diet: The cornerstone of managing Type 1 Diabetes Mellitus is a balanced diet. Balancing daily intake of nutrients can play an important role in managing diabetes. A healthy diet plan monitoring calorie intake is paramount.

Healthier carbohydrates are those rich in fiber and with a lower glycemic index (GI). Foods with lower GI digest slowly. This leads to a gradual increase in blood sugar instead of a sudden spike. A sudden spike in blood sugar is bad for health.

A diverse diet with plenty of fruits, vegetables, lean proteins, and healthy fats is essential. Balancing fat intake is essential, as higher fat levels may contribute to weight gain. Regular meal timing and portion control can help stabilize blood sugar levels(10^✔ ✔Trusted Source

How Physical Activity Helps: Encouraging all individuals with type 1 diabetes to participate in regular physical activity is important. Simple activities like walking, swimming, or cycling can be easy to follow and fun. Regular exercise improves insulin sensitivity and helps with better blood sugar control.

During exercise, muscles need more energy, which comes from glucose in the blood and stored glucose in muscles (glycogen). The body becomes more sensitive to insulin during or after exercise, needing less insulin.

Before a person with type 1 diabetes exercises, it's important to consider factors such as the intensity of the exercise, blood sugar levels before and after, as well as the amount and type of insulin. It's crucial to consult with a healthcare professional for personalized advice on managing these factors(11^✔ ✔Trusted Source

Insulin Intake: Treatment mainly includes insulin replacement therapy. Insulin is either administered via injections or pumps.

Oral pills do not work as the stomach acids tend to destroy insulin. Healthcare providers use different insulin types based on blood sugar levels and the diabetic management plan. These include rapid-acting, short-acting, intermediate-acting, and long-acting insulin. The number of injections also varies accordingly.

Stress Management: Dealing with Type 1 Diabetes Mellitus can be extremely stressful for children due to lifestyle restrictions. They are learning to manage this stress using relaxation techniques, yoga, meditation, and breathing exercises, getting emotional support, and replacing negative thoughts with positive ones. Spending quality time with friends and family can also contribute to their overall well-being(13^✔ ✔Trusted Source

Routine check-ups: Regular appointments with medical professionals are essential to monitor the progression of the disease. Evaluate any arising complications, and modify treatment strategies when necessary. Following prescribed medication regimens and lifestyle modifications is vital for sustained well-being.

Regular visits to healthcare providers are crucial for tracking the progress of the condition. Assessing potential complications and adjusting treatment plans as needed is a key factor. Adherence to prescribed medications and lifestyle changes is key for long-term health.

Prevention of Type 1 Diabetes

Preventing type 1 diabetes is not possible, unlike type 2 diabetes. This is because type 1 diabetes is an autoimmune disease, unlike type 2 diabetes which is partly a lifestyle disease as well(15^✔ ✔Trusted Source

Type 1 Diabetes Complications

Complications associated with type 1 diabetes underscore the importance of diligent management. Regular medical check-ups, blood sugar monitoring, and adherence to treatment plans help mitigate the risk of complications such as cardiovascular issues and nerve damage.

Ketoacidosis

With low levels of glucose for cells to function, the body breaks down fat cells resulting in the formation of chemicals called ketones. The liver releases sugars to help, but since there is no insulin, it results in a build-up of sugar in the bloodstream.

Ketoacidosis is a dangerous condition that can occur when there is an excess of acid, sugar, and a lack of water. If left untreated, ketoacidosis can be fatal(16^✔ ✔Trusted Source
