**Diabetes** ***What is diabetes?*** Diabetes is a chronic medical condition characterized by high blood sugar levels. It occurs when the body either doesn't produce enough insulin (a hormone that regulates blood sugar) or cannot effectively use the insulin it produces. There are two main types: **Type 1 Diabetes:** **Type 2 Diabetes:** **The mechanism involve in diabetes.** ***Type 1 Diabetes***: **Autoimmune Reaction**: **Insulin Deficiency**: ***Type 2 Diabetes:*** Insulin Resistance: Impaired Insulin Secretion: Increased Gluconeogenesis: **Common Factors:** **Genetics:** Family history can increase the risk of both types. **Lifestyle:** Poor diet, lack of exercise, and obesity are significant risk factors, particularly for Type 2. **Hormonal Influences:** Other hormones can affect insulin action and glucose metabolism, such as cortisol and glucagon. **TREATMENT FOR DIABETES** ***Type 1 Diabetes:*** **1.Insulin Therapy:** **2. Monitoring Blood Sugar:** **3. Dietary Management**: **4. Physical Activity:** ***Type 2 Diabetes*** **1. Lifestyle Changes: Diet**: Emphasis on whole foods, high fiber, and low sugar Exercise: Regular physical activity to help control weight and limprove insulin sensitivity **2.Oral Medications:** Various medicationis (e.g.metformin) to help lower blood sugar levels or improve insulin sensitivity. **3. Insulin Therapy:** Sometimess required if blood sugar levels cannot be controlled with oral medications alone. **4. Monitoring Regular blood sugar** testing to guide treatment decisions Common Approaches for Both Managing diabetes involves lifestyle changes, monitoring blood sugar levels, and sometimes medication or insulin therapy. **Maltose Malabsorption** **​Maltose malabsorption** is a condition where the body cannot properly digest maltose due to a deficiency of the enzyme maltase. This leads to digestive issues and potential nutritional complications. **Maltose**: A disaccharide sugar formed from two glucose molecules. It\'s found in various starchy foods like bread, pasta, and potatoes. **Maltase**: An enzyme produced in the small intestine. It\'s responsible for breaking down maltose into glucose, which can then be absorbed. **Malabsorption** - is a digestive disorder that prevents your body from effectively absorbing nutrients from your food. It has many causes, but most of them involve damage to the mucous lining of your small intestine, where most absorption happens. You can think of digestion as a three-part process. The first part is breaking down food into digestible pieces. The second part is absorbing all the nutrients in your food. And the third part is eliminating the waste that is left over when all the good stuff has been absorbed. **Development** The Process of Maltose Malabsorption **Dietary Intake**: When maltose-rich foods are consumed, they reach the small intestine. **Enzyme Deficiency**: Due to a deficiency in maltase, the body is unable to efficiently break down maltose. **Undigested Maltose**: The undigested maltose travels to the large intestine. **Bacterial Fermentation**: Bacteria in the large intestine ferment the maltose, producing gases like hydrogen, carbon dioxide, and methane. **Symptoms** Common symptoms include: **Diagnosis** **Management & Treatment** **a.** [Dietary Adjustments]: Limiting maltose-containing foods **b.** [Enzyme Supplements]: Prescribed in some cases **c.** [Nutritional Support]: Working with a dietitian **Case Example** ​A patient with chronic digestive issues undergoes a hydrogen breath test, which indicates maltose malabsorption. Treatment involves a low-maltose diet and possibly enzyme supplements. **Conclusion** ​While maltose malabsorption can cause significant discomfort, proper diagnosis and management, primarily through dietary modifications, can greatly improve quality of life for affected individuals. **Lactose intolerance** People with lactose intolerance are unable to fully digest the sugar (lactose) in milk. As a result, they have diarrhea, gas and bloating after eating or drinking dairy products. The condition, which is also called lactose malabsorption, is usually harmless, but its symptoms can be uncomfortable. Too little of an enzyme produced in your small intestine (lactase) is usually responsible for lactose intolerance. You can have low levels of lactase and still be able to digest milk products. But if your levels are too low you become lactose intolerant, leading to symptoms after you eat or drink dairy. **[Lactase deficiency\ ]{.smallcaps}**in people who have a lactase deficiency, the small intestine produces low levels of lactase and cannot digest much lactose **Lactose malabsorption**\ lactase deficiency may cause lactose malabsorption. In lactose malabsorption, undigested lactose passes to colon. The colon part of the large intestine, absorbs water **Symptoms and causes of lactose intolerance** **Symptoms** - Abdominal pain - Bloating - Diarrhea - Flatulence - Nausea **Causes** - Injury to the small intestine due to infections, diseases, or other conditions like crohn's disease or celiac disease, which may cause it to make less lactase. - Premature birth, where the small intestine may not make enough lactase for a short time after birth. - Hereditary factors, as lactose intolerance often runs in families. - In some cases, the small intestine stops making lactase after an injury or after a disease or infection. - In very rare cases, people are born with an inability to make any lactase at all. **Types of lactose intolerance** **1. Primary lactose intolerance** People who develop primary lactose intolerance --- the most common type --- start life producing enough lactase. Infants, who get all their nutrition from milk, need lactase. **2. Secondary lactose intolerance** This form of lactose intolerance occurs when your small intestine decreases lactase production after an illness, injury or surgery involving your small intestine. Diseases associated with secondary lactose intolerance include intestinal infection, celiac disease, bacterial overgrowth and Crohn\'s disease. **3. Congenital or developmental lactose intolerance** Babies can be born with lactose intolerance due to lack of lactace, which is inherited in an autosomal recessive pattern requiring both parents to pass on the same gene variant. **Medication for Lactose intolerance** To lower the amount of lactose in your diet: - Limit milk and other dairy products - Include small servings of dairy products in your regular meals - Eat and drink lactose-reduced ice cream and milk - Add a liquid or powder lactase enzyme to milk to break down the lactose **Congenital Insensitivity to Pain with Anhidrosis (CIPA)** Rare genetic disorder (1 in 125 million newborns); a type of congenital hereditary sensory and autonomic neuropathy (HSAN). **Key Features:** - No Pain Sensation (insensitivity to pain) - No Sweating(anhidrosis) - Developmental Delays (slower growth and learning) **Pathology** - **Genetic Cause: Mutations in the \*\*NTRK1\*\* gene (neurotrophic tyrosine receptor kinase 1).**  **Symptoms** - **Skin infections (Staphylococcus aureus).** - **Self-Injury: Accidental biting of lips, fingers, or tongue.** - **Overheating: high body temperatures (hyperthermia).** **Complications** - **Broken Bones: unnoticed injuries.** - **Bone Infections (osteomyelitis).** - **Dental cavities and gum disease** **Treatment** - **No Cure** - Focus on prevention and management. **Management** - **Regular Check-ups** - **Braces for Support: To assist with fractures.** - **Surgery** **Other Considerations** Regular Medical Visits: Education on Safety Emotional Support **Ongoing Care** **[1. Team Approach: ]** - **Geneticists** - **Neurologists** - **Dentists** - **Physical therapists.** **[2. Thermoregulation Strategies]** **Hyperferritinemia-cataract syndrome** - hyperferritinemia-cataract syndrome is a disorder characterized by an excess of an iron storage protein called ferritin in the blood (hyperferritinemia) and tissues of the body. - a buildup of this protein begins early in life, leading to clouding of the lenses of the eyes (cataracts). - In affected individuals, cataracts usually develop in infancy, rather than after age 60 as typically occurs in the general population. - cataracts that are not removed surgically cause progressive dimming and blurriness of vision because the clouded lenses reduce and distort incoming light. although the hyperferritinemia in this disorder does not usually cause any health problems other than cataracts, the elevated ferritin levels in the blood can be mistaken for a sign of certain liver disorders. - These conditions result in excess iron in the body and may be treated by blood-drawing. however, individuals with hyperferritinemiacataract syndrome do not have an excess of iron, and with repeated blood draws will develop reduced iron levels leading to a low number of red blood cells (anemia). - therefore, correct diagnosis of hyperferritinemia-cataract syndrome is important to avoid unnecessary treatments or invasive test procedures such as liver biopsies. this condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. frequency: hyperferritinemia-cataract syndrome has been estimated to occur in 1 in 200,000 individuals. **symptoms:** elevated levels of ferritin in the blood, early-onset cataracts and sometimes diabetes and liver disease. pathology: hyperferritinemia-cataract syndrome: caused by mutations in the ftl gene. ftl gene function: provides instructions for the ferritin light chain, a subunit of ferritin. ferritin structure: composed of 24 subunits (ferritin light and heavy chains) forming a hollow spherical molecule. ferritin role: stores and releases iron in cells, with a capacity to hold up to 4,500 iron atoms. iron regulation: ferritin helps regulate iron levels in cells and tissues. mutations location: found in the iron responsive element (ire) segment of the ftl gene. ire function: normally binds to iron regulatory protein (irp) to stop ftl gene activity when iron levels are low. mutation effect: prevents binding with irp, disrupting the regulation of ferritin production and leading to excess ferritin formation. **medication/treatment:** - cataract surgery - patients are treated by cataract surgery when they suffer visual impairment due to cataracts formation. - hyperferritinemia is not associated with iron overload and doesn\'t require treatment. **safety measures** 1\. regular eye examinations: ensure frequent visits to an ophthalmologist to monitor cataract progression and assess vision changes. 2\. sun protection: encourage the use of uv-protective sunglasses to minimize additional eye damage from sunlight. 3\. avoidance of iron supplements: patients should avoid iron-rich supplements and foods that can exacerbate hyperferritinemia. 4\. education on symptoms: educate patients and families on recognizing symptoms related to vision changes and potential complications. monitoring 1\. ferritin levels: regular blood tests to monitor ferritin levels, helping to manage iron overload. 2\. visual acuity tests: periodic assessments of vision to track changes and determine if surgical intervention is needed. 3\. liver function tests: since iron overload can affect liver function, regular monitoring of liver enzymes is essential. 4\. genetic counseling: for families, genetic testing and counseling can help understand inheritance patterns and implications for future generations. **ongoing care** 1\. multidisciplinary team: involve a team including an ophthalmologist, hematologist, and geneticist for comprehensive care. 2\. cataract surgery: when cataracts significantly impact vision, discuss surgical options and timing with the ophthalmologist. 3\. dietary management: work with a nutritionist to create a balanced diet low in iron and rich in antioxidants. 4\. psychosocial support: provide access to counseling or support groups for emotional and social support, particularly if vision impairment affects daily living. **Important Key Terms:**  **Insulin**: A hormone produced by the pancreas that regulates blood sugar levels by facilitating the uptake of glucose into cells.  **Gluconeogenesis**: A metabolic process by which glucose is produced from non-carbohydrate precursors, such as amino acids and glycerol, primarily in the liver.  **Congenital**: Refers to a condition or trait that is present from birth, which can be due to genetic or environmental factors during pregnancy.  **Autosomal**: Relates to autosomes, which are the non-sex chromosomes. Autosomal traits or disorders are inherited regardless of the sex of the offspring.  **Hypoglycemia**: A condition characterized by abnormally low levels of glucose in the blood, which can cause symptoms like dizziness, confusion, and, in severe cases, loss of consciousness.  **Allopurinol**: A medication used to lower uric acid levels in the blood, commonly prescribed for conditions like gout or kidney stones.  **Hydrogen Breath Test**: A diagnostic test used to measure the amount of hydrogen in the breath after consuming a specific carbohydrate. It helps diagnose conditions like lactose intolerance or small intestinal bacterial overgrowth (SIBO).  **Cataracts**: A clouding of the lens in the eye that can lead to decreased vision. Cataracts often develop with age or due to other factors such as diabetes.  **Hepatomegaly**: An enlargement of the liver, which can be caused by a variety of conditions, including liver disease, infections, or metabolic disorders. **Diabetes** **Questions** 1. **1.What are the primary differences between Type 1 and Type 2 diabetes in terms of their causes?** 2. **How does insulin resistance contribute to the development of Type 2 diabetes?** 3. **What is diabetes primarily characterized by?** 4. **Type 1 Diabetes is mainly diagnosed in which age group?** 5. **In Type 1 Diabetes, what attacks the insulin-producing cells?** 6. **Which of the following describes insulin resistance in Type 2 Diabetes?** 7. **What is a common lifestyle risk factor for Type 2 Diabetes?** 8. **What is a standard treatment for Type 1 Diabetes?** 9. **What type of medication is often used for Type 2 Diabetes management?** 10. **What dietary management is crucial for individuals with Type 1 Diabetes?** 11. **Which hormone can influence insulin action and glucose metabolism?** 12. **What is a common approach to managing both Type 1 and Type 2 Diabetes?** **Glycogen Storage Diseases (GSD)** 1. **What is the primary cause of Glycogen Storage Diseases (GSD)?** 2. **Which of the following is a common symptom of GSD type 1?** 3. **What is the typical blood glucose level that indicates hypoglycemia?** 4. **Which test is used to assess liver health in suspected GSD cases?** 5. **What treatment is commonly used to manage high cholesterol levels in patients with GSD?** 6. **What dietary strategy can help prevent low blood sugar episodes in GSD patients?** 7. **How many types of Glycogen Storage Diseases (GSD) are identified?** 8. **Which of the following conditions can elevate uric acid levels in GSD patients?** 9. **What is the primary objective of enzyme replacement therapy (ERT) for GSD?** 10. **Which option is NOT a symptom of glycogen storage disease?** **LACTOSE INTOLERANCE** 1. **What is lactose intolerance primarily caused by?** 2. **Which of the following is NOT a symptom of lactose intolerance?** 3. **What is the term used for the condition where undigested lactose passes to the colon?** 4. **Which type of lactose intolerance results from a decrease in lactase production after an illness or injury?** 5. **What is the most common type of lactose intolerance?** 6. **Which of the following is a hereditary factor that may cause lactose intolerance?** 7. **What can be added to milk to help break down lactose for lactose intolerant individuals?** 8. **Infants need lactase to digest which type of nutrition?** 9. **Which of the following describes congenital lactose intolerance?** 10. **What dietary change is suggested for managing lactose intolerance?** **Maltose Malabsorption** 1. **What is maltose?** 2. **What is the primary enzyme responsible for breaking down maltose?** 3. **What common digestive issue can result from maltose malabsorption?** 4. **Which test is commonly used to diagnose maltose malabsorption?** 5. **What is a potential consequence of maltose malabsorption if not managed?** 6. **How can one manage maltose malabsorption?** 7. **What happens to undigested maltose in the large intestine?** 8. **What type of diet is suggested for managing maltose malabsorption?** 9. **Which symptom is least likely to be associated with maltose malabsorption?** 10. **What is malabsorption at its core?** **Galactosemia** 1. **What is the primary cause of galactosemia?** 2. **How is galactosemia inherited?** 3. **What is the only treatment for galactosemia?** 4. **What is one of the early symptoms of galactosemia in infants?** 5. **In which stage of life can a child begin eating solid foods while managing galactosemia?** 6. **Which enzyme is primarily deficient in classic galactosemia (Type I)?** 7. **What kind of diet must individuals with galactosemia adhere to?** 8. **What toxic accumulation occurs due to galactosemia?** 9. **What is a potential long-term complication for females with galactosemia?** 10. **What method is used for newborn screening to detect galactosemia?** **Additional question** 1. **What is the primary role of insulin in the body?** 2.

Type 1 diabetes is an autoimmune condition where the immune system attacks insulin-producing cells in the pancreas, leading to insulin deficiency. In contrast, Type 2 diabetes is often caused by insulin resistance, where the body\'s cells become less responsive to insulin, typically influenced by lifestyle factors. -- 2. Insulin resistance makes it difficult for glucose to enter the cells, leading to higher blood sugar levels. Over time, the pancreas may not produce enough insulin to compensate, which exacerbates the problem. 3. High blood sugar levels 4. Adolescents and young adults 5. Immune system 6.
