Type 1 Diabetes Mellitus: A Chronic Disorder

Type 1 diabetes mellitus, also known as type 1 diabetes, is a chronic disorder characterized by high levels of glucose in the blood [13]. Glucose is the main source of energy for the body's cells. When a person eats food—a plate of pasta or an apple, for instance—the food passes into the stomach, where it is broken down into individual nutrients, including glucose.

Insulin Deficiency

In type 1 diabetes, the pancreas doesn't make enough insulin to help glucose enter cells for energy [7]. As a result, glucose builds up in the blood. This can lead to various complications if left untreated or poorly managed.

Symptoms and Diagnosis

The symptoms of type 1 diabetes usually come on suddenly and strongly [5]. They include increased thirst and urination, fatigue, and blurred vision. Type 1 diabetes is diagnosed most commonly between ages 10 and 16 [6].

Management and Prevention

While there's no known way to prevent type 1 diabetes, it can be managed successfully with daily insulin administration [14]. Additionally, managing blood glucose, blood pressure, and cholesterol levels, as well as following a self-care plan, can help prevent or delay the health problems associated with diabetes [12].

Global Prevalence

Type 1 diabetes affects millions of people worldwide. In 2017, there were approximately 9 million people living with type 1 diabetes, with the majority residing in high-income countries [14].

Early Warning Signs of Type 1 Diabetes Mellitus

Type 1 diabetes mellitus can develop suddenly, especially in children, with symptoms appearing over several days, weeks, or months. The early warning signs of type 1 diabetes are crucial to detect and treat the condition early on.

• Increased thirst and urination: One of the most common symptoms of type 1 diabetes is an increased urge to drink fluids, leading to frequent urination (polyuria). This occurs due to high blood sugar levels that cause the kidneys to produce more urine. [2][3]
• Weight loss: Despite eating normally, people with type 1 diabetes may experience unexplained weight loss due to the body's inability to use glucose for energy. [4][13]
• Increased hunger: As the body struggles to regulate blood sugar levels, individuals may feel hungrier than usual, even after consuming a meal. [2][3]
• Fatigue: Type 1 diabetes can cause fatigue, as the body works harder to try and manage high blood sugar levels. [4][13]
• Blurry vision: High blood sugar levels can damage the blood vessels in the eyes, leading to blurry vision or changes in vision. [2][3]

Other Possible Symptoms

In some cases, people with type 1 diabetes may experience other symptoms, including:

• Slow-healing cuts and sores: High blood sugar levels can impair the body's ability to heal wounds.
• Frequent infections: Type 1 diabetes can weaken the immune system, making it harder for the body to fight off infections.

Important Note

It is essential to seek medical attention if you or a loved one experiences any of these symptoms. Early detection and treatment can significantly improve outcomes and prevent complications associated with type 1 diabetes mellitus. [12][14]

Diagnostic Tests for Type 1 Diabetes Mellitus

Type 1 diabetes mellitus (T1DM) can be diagnosed through various tests, which help identify the presence of autoantibodies and other biomarkers associated with the disease. Here are some common diagnostic tests used to diagnose T1DM:

• Antibody testing: This blood test detects autoantibodies that indicate the presence of T1DM. The presence of specific antibodies such as GAD, IAA, and IA-2 is often used to confirm a diagnosis of T1DM [9].
• Fasting plasma glucose (FPG): FPG measures the level of glucose in the blood after an overnight fast. Elevated levels can indicate diabetes or prediabetes [7].
• Oral glucose tolerance test (OGTT): OGTT measures the body's ability to regulate blood sugar levels after consuming a sugary drink. Abnormal results may suggest T1DM or other forms of diabetes [8].
• A1C: The A1C test measures average blood sugar levels over the past 2-3 months. Elevated levels can indicate diabetes, while lower levels may suggest prediabetes [4].
• Random glucose testing: This is a primary screening test for T1DM, which involves taking a blood sample at any time of day [5].

Other Tests

In addition to these diagnostic tests, other factors such as age and symptoms are also considered when diagnosing T1DM. For example:

• Age: The average age of diagnosis for T1DM is approximately 32 years in adults [15].
• Symptoms: Common symptoms of T1DM include increased thirst and urination, which can be similar to those experienced with other conditions.

Types of Medications for Type 1 Diabetes

Type 1 diabetes mellitus requires insulin therapy to manage blood sugar levels. In addition to insulin, several medications are available to help control the disease.

• Glargine (Lantus, Toujeo Solostar, Basaglar): This long-acting insulin analog is used to control blood glucose levels throughout the day [1].
• Detemir (Levemir): Another long-acting insulin analog that helps regulate blood sugar levels [2].
• Degludec (Tresiba): A once-daily, ultra-long-acting insulin analog that provides 42 hours of glycemic control [3].

New Medications for Type 1 Diabetes

Recently approved medications include:

• Teplizumab (Tzield): An immunomodulatory therapy that helps preserve beta-cell function and reduce the need for insulin in people with stage 2 type 1 diabetes [4].
• Lantidra: Approved for adults with type 1 diabetes who are unable to achieve target glycated hemoglobin levels despite optimal insulin therapy [5].

Other Medications

In addition to these specific medications, other treatments may be used to manage type 1 diabetes:

• Dulaglutide (Trulicity): A glucagon-like peptide-1 receptor agonist that helps lower blood sugar levels [6].
• Exenatide (Byetta): Another GLP-1 receptor agonist that aids in glucose control [7].

Insulin Therapy

It's essential to note that insulin therapy remains the primary treatment for type 1 diabetes, and most people with this condition will require insulin injections to manage their blood sugar levels [8].

Differential Diagnoses for Type 1 Diabetes Mellitus

Type 1 diabetes mellitus (T1DM) can be challenging to diagnose, as it shares similar symptoms with other conditions. Here are some differential diagnoses that should be considered:

• Diabetes Insipidus: This condition is characterized by the inability of the kidneys to regulate fluids in the body, leading to excessive thirst and urination.
• Monogenic Diabetes: Also known as maturity-onset diabetes of the young (MODY), this is a rare form of diabetes caused by genetic mutations that affect insulin production.
• Pediatric Hyperthyroidism: This condition occurs when the thyroid gland produces too much thyroid hormone, leading to symptoms such as weight loss, increased appetite, and fatigue.
• Pheochromocytoma: A rare tumor of the adrenal gland that can cause high blood pressure, sweating, and other symptoms.
• Renal Glucosuria: A condition where the kidneys are unable to reabsorb glucose from the urine, leading to excessive glucose in the urine.
• Salicylate Toxicity: Poisoning caused by taking too much aspirin or other salicylates.

These conditions can present with similar symptoms to T1DM, such as weight loss, polyuria, and polydipsia. It's essential to consider these differential diagnoses when evaluating patients for T1DM.
