Symptoms:
frequent urination (polyuria); excessive thirst (polydipsia); unintended weight loss; fatigue; blurred vision; slow wound healing; recurrent infections
Root Cause:
The immune system attacks and destroys insulin-producing beta cells in the pancreas, leading to a lack of insulin production and resul.ting in hyperglycemia.

Accounts for approximately 5–10% of all diabetes cases; often diagnosed in childhood but can occur at any age.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.

Latent Autoimmune Diabetes in Adults (LADA)
Specialty: Diabetes and Endocrinology
Category: Diabetes Mellitus and Related Disorders
Sub-category: Type 2 Diabetes Mellitus
Symptoms:
gradual onset of hyperglycemia; excessive thirst (polydipsia); frequent urination (polyuria); fatigue; blurred vision; weight loss
Root Cause:
A slow-progressing autoimmune destruction of pancreatic beta cells, resulting in reduced insulin production. Often misdiagnosed as type 2 diabetes due to its slower progression.
How it's Diagnosed: videos
Diagnosed through positive islet autoantibodies and gradual insulin dependence.
Treatment:
Treated initially with oral antidiabetics (e.g., metformin) and progression to insulin therapy as beta-cell function declines.

Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Family history of autoimmune conditions, genetic predisposition (e.g., certain HLA genes), and environmental factors.
Prognosis:
The expected outcome or course of the condition over time.

Sub-category: Type 2 Diabetes Mellitus
Symptoms:
increased hunger (polyphagia); frequent urination (polyuria); excessive thirst (polydipsia); fatigue; blurred vision; slow-healing wounds; darkened skin patches (acanthosis nigricans)
Root Cause:
Impaired cellular response to insulin leads to reduced glucose uptake, causing the pancreas to overproduce insulin to compensate. This contributes to beta-cell dysfunction and relative insulin deficiency over time.
How it's Diagnosed: videos
Blood tests such as fasting glucose levels, HbA1c (glycated hemoglobin), oral glucose tolerance test (OGTT), and insulin levels; physical exam identifying symptoms like acanthosis nigricans.
Treatment:
Lifestyle interventions (diet, exercise), weight management, medications to improve insulin sensitivity or lower blood glucose, and in some cases, insulin therapy.
Medications:
Metformin
Prevalence:
How common the health condition is within a specific population.
Insulin resistance is a hallmark of prediabetes and Type 2 diabetes, affecting up to 39% of the global adult population, with higher rates in obese and sedentary individuals.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Obesity, sedentary lifestyle, family history of diabetes, polycystic ovary syndrome (PCOS), age over 45, and certain ethnicities (e.g., African American, Hispanic, Asian).
Prognosis:
The expected outcome or course of the condition over time.
With proper management, progression to diabetes can be delayed or prevented. Uncontrolled, it leads to chronic hyperglycemia and complications such as cardiovascular disease and neuropathy.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Increased risk of Type 2 diabetes, cardiovascular disease, fatty liver disease, kidney damage, and nerve damage (neuropathy).
Diabetes during pregnancy
Specialty: Diabetes and Endocrinology
Category: Diabetes Mellitus and Related Disorders
Sub-category: Gestational Diabetes Mellitus (GDM)
Symptoms:
increased thirst; frequent urination; fatigue; blurred vision; unexplained weight changes; nausea; slow-healing infections
Root Cause:
Insulin resistance due to hormonal changes during pregnancy, combined with an inability of the pancreas to produce sufficient insulin to maintain normal glucose levels.
How it's Diagnosed: videos
Diagnosis is through glucose screening tests such as the oral glucose tolerance test (OGTT) conducted during the second trimester (usually between 24 and 28 weeks of pregnancy).
Treatment:
Management involves dietary modifications, regular physical activity, blood glucose monitoring, and, if needed, medications to regulate blood sugar levels.
Medications:
Insulin therapy is the primary treatment if blood sugar cannot be controlled through lifestyle changes. Additionally, oral medications such as metformin (a biguanide that improves insulin sensitivity) or glyburide (a sulfonylurea that increases insulin secretion) may be prescribed in some cases.
Prevalence:
How common the health condition is within a specific population.
Gestational diabetes affects approximately 6-9% of pregnancies globally, with higher rates in certain populations.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Family history of diabetes; overweight or obesity; advanced maternal age; previous history of gestational diabetes; ethnic predisposition (e.g., South Asian, African-American, Hispanic); polycystic ovary syndrome (PCOS)

How it's Diagnosed: videos
Clinical suspicion based on symptoms, confirmed by a supervised 72-hour fasting test demonstrating hypoglycemia with inappropriately high insulin levels, C-peptide, and proinsulin. Imaging (CT, MRI, or endoscopic ultrasound) is used to localize the tumor.
Treatment:
Surgical removal of the tumor is the primary treatment. In non-surgical cases, medical management focuses on controlling hypoglycemia.
Medications:
Diazoxide (reduces insulin secretion, potassium channel activator) and somatostatin analogs like octreotide (inhibit insulin release).
Prevalence:
How common the health condition is within a specific population.
Insulinomas are rare, with an estimated incidence of 1-4 cases per million people annually.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.

Treatment:
Dietary management, surgery (if caused by an insulinoma), or medications to regulate insulin secretion.
Medications:
Diazoxide (a potassium channel opener that inhibits insulin secretion) or octreotide (a somatostatin analog to suppress insulin release).
Prevalence:
How common the health condition is within a specific population.
Rare; congenital forms are more common in neonates, while insulinomas occur in about 1-4 per million people annually.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.

Snake venom poisoning
Specialty: Toxicology
Category: Biological and Natural Toxins
Sub-category: Animal Toxins
Symptoms:
pain at the bite site; swelling; difficulty breathing; nausea; vomiting; dizziness; weakness; blurred vision; bleeding; paralysis
Root Cause:
Envenomation by the venom of a snake, which contains proteins that can damage tissue, blood vessels, and organs.
How it's Diagnosed: videos
Diagnosis is based on clinical signs and symptoms, the type of snake (if known), and laboratory tests like blood clotting studies, complete blood count (CBC), and snake venom detection kits.
Treatment:
Antivenom administration is the primary treatment, along with supportive care such as fluid management, pain relief, and respiratory support.
Medications:
The main treatment is antivenom, which is a specific antibody designed to neutralize venom toxins. Pain relief can be managed with opioids or non-steroidal anti-inflammatory drugs (NSAIDs), depending on the severity of the pain. In severe cases, corticosteroids may be used to reduce inflammation and swelling. Anticoagulants may be used for clotting issues, and antibiotics may be given if secondary infections are a concern.
