Obsolete Type 1 Diabetes Mellitus 9: A Historical Definition

Type 1 diabetes mellitus 9, also known as IDDM 9 or Insulin-Dependent Diabetes Mellitus 9, was an outdated term used to describe a specific type of diabetes. According to the definition provided in the context (DOID:0110748), it is now considered obsolete.

Key Characteristics

• This term was previously used to describe a subtype of diabetes characterized by insulin deficiency.
• It was manifested by the sudden onset of severe hyperglycemia and rapid progression of the disease.
• The exact characteristics and symptoms associated with this term are no longer relevant, as it has been replaced by more modern and accurate definitions.

Replacement Terms

The terms "Type 1 includes immune mediated and idiopathic forms of β cell dysfunction which lead to absolute insulin deficiency" (DOID:0110748) and "Juvenile-onset diabetes" (Peds

Classic Catabolic Symptoms

The classic catabolic symptoms of type 1 diabetes mellitus, as mentioned in [9], include:

• Polyuria (frequent urination)
• Polydipsia (extreme thirst)
• Severe weight loss
• Vomiting

These symptoms can develop rapidly and are often severe. In the case described in [9], the patient experienced these symptoms for 2 weeks before seeking medical attention.

Other Symptoms

In addition to the classic catabolic symptoms, other signs and symptoms of type 1 diabetes mellitus may include:

• Fatigue
• Hunger
• Blurry vision
• Irritability

These symptoms can vary in severity and may develop more slowly than the classic catabolic symptoms.

Diagnostic Tests for Type 1 Diabetes Mellitus

Type 1 diabetes mellitus (T1DM) was previously diagnosed using various blood tests, which are now considered obsolete due to advancements in medical technology. Here are some of the diagnostic tests that were once used to diagnose T1DM:

• C-peptide test: This test measures the level of C-peptide in the blood, which is a byproduct of insulin production. A low C-peptide level was indicative of T1DM (5).
• Insulin assay: This test measured the level of insulin in the blood, and a low insulin level was suggestive of T1DM (10).
• Diabetes antibody panel: This test checked for the presence of antibodies against the pancreas, which

Treatment Options for Type 1 Diabetes

According to various sources, people with type 1 diabetes almost always require insulin therapy and will become very sick without it [8]. In addition to insulin, some individuals may also be prescribed oral medications such as Metformin, although this is more commonly used in type 2 diabetes patients who have insulin resistance [15].

Insulin Therapy

The primary treatment for type 1 diabetes is insulin injections, which make up for the lack of insulin produced by the body. Most people with type 1 diabetes need two to four injections per day, and must also properly regulate their dietary intake and dose of insulin [12].

Other Medications

While not as common, some individuals with type 1 diabetes may be prescribed medications such as Metformin, which can help improve insulin sensitivity. However, it's essential to note that these medications are typically used in conjunction with insulin therapy, rather than as a replacement for it.

Important Considerations

It's crucial for individuals with type 1 diabetes to work closely with their healthcare provider to develop an effective treatment plan. This may involve regular blood sugar monitoring, adjustments to diet and exercise routines, and careful management of insulin doses.

References: [8] People with type 2 diabetes require insulin as well... [12] Treatment. Treatment of type 1 diabetes requires daily insulin injections. [15] Although insulin is the main medication for type 1 diabetes, some people with type 1 diabetes may also be prescribed a tablet called Metformin.

Differential Diagnoses for Obsolete Type 1 Diabetes Mellitus

When considering differential diagnoses for what appears to be obsolete type 1 diabetes mellitus (T1DM), several conditions should be taken into account. These include:

• Type 2 Diabetes Mellitus: This is the most common form of diabetes and can often present with similar symptoms to T1DM, such as hyperglycemia, polyuria, and polydipsia [4].
• Maturity-Onset Diabetes of the Young (MODY): MODY is a rare form of diabetes that typically presents in young individuals without obesity. It may be misdiagnosed as either Type 1 or Type 2 diabetes [6].
• Psychogenic Polydipsia: This condition involves excessive thirst and water intake, often leading to hyperglycemia. It can mimic the symptoms of T1DM and should be considered in differential diagnoses [4].

Other Considerations

In addition to these conditions, other factors may contribute to the differential diagnosis of obsolete T1DM. These include:

• Genetic Syndromes: Certain genetic syndromes, such as Down syndrome, can increase the risk of developing diabetes [3].
• Pancreatic Insufficiency: Conditions that affect pancreatic function, such as cystic fibrosis, may lead to diabetes [3].
