Diabetes

HDiabetes mellitus, often simply referred to as diabetes, is a group of metabolic diseases in which a person has high blood sugar, either because the body does not produce enough insulin, or because cells do not respond to the insulin that is produced. This high blood sugar produces the classical symptoms of polyuria (frequent urination), polydipsia (increased thirst) and polyphagia (increased hunger).
There are three main types of diabetes :

1.Type 1 diabetes

Type 1 diabetes mellitus is characterized by loss of the insulin-producing beta cells of the islets of Langerhans in the pancreas leading to insulin deficiency. This type of diabetes can be further classified as immune-mediated or idiopathic

2.Type 2 diabetes

Type 2 diabetes mellitus is characterized by insulin resistance which may be combined with relatively reduced insulin secretion. However, the specific defects are not known. Diabetes mellitus due to a known defect are classified separately. Type 2 diabetes is the most common type.

3. Gestational diabetes

Gestational diabetes mellitus (GDM) resembles type 2 diabetes in several respects, involving a combination of relatively inadequate insulin secretion and responsiveness. Gestational diabetes is fully treatable but requires careful medical supervision. throughout the pregnancy.

Causes

The cause of diabetes depends on the type.
1.Type 1 diabetes:- is partly inherited and then triggered by certain infections, with some evidence pointing at Coxsackie B4 virus. There is a genetic element in individual susceptibility to some of these triggers which has been traced to particular HLA genotypes (i.e., the genetic “self” identifiers relied upon by the immune system). However, even in those who have inherited the susceptibility, type 1 diabetes mellitus seems to require an environmental trigger.
2.Type 2 diabetes:- is due to primarily to lifestyle factors and genetics.
3.Gestational diabetes:- Genetic defects of ß-cell Function Genetic defects in insulin processing or insulin action Exocrine Pancreatic Defects
Endocrinopathies

Symptoms

• Increased thirst
• Increased urination
• Constant hunger
• Significant weight loss in when constantly eating
• Fatigue
• Dizziness
• Blurred vision

Foot Diabetes

Diabetic Foot Care Overview:-

Diabetes can also decrease the body’s ability to fight infection.
Foot problems commonly develop in people with diabetes and can quickly become serious.

Diabetic Foot Care Causes:-

Several risk factors increase a person with diabetes chances of developing foot problems and diabetic infections in the legs and feet.
Footwear: Poorly fitting shoes are a common cause of diabetic foot problems. If the patient has red spots, sore spots, blisters, corns, calluses, or consistent pain associated with wearing shoes, new properly fitting footwear must be obtained as soon as possible.
If the patient has common foot abnormalities such as flat feet,bunions, or hammertoes, prescription shoes or shoe inserts may be necessary.
Poor circulation: Especially when poorly controlled, diabetes can lead to accelerated hardening of the arteries or atherosclerosis. When blood flow to injured tissues is poor, healing does not occur properly.
Trauma to the foot: Any trauma to the foot can increase the risk for a more serious problem to develop.

Infections:-

Athlete’s foot, a fungal infection of the skin or toenails, can lead to more serious bacterial infections and should be treated promptly. Ingrown toenails should be handled right away by a foot specialist. Toenail fungus should also be treated.
Smoking: Smoking any form of tobacco causes damage to the small blood vessels in the feet and legs. This damage can disrupt the healing process and is a major risk factor for infections and amputations. The importance of smoking cessation cannot be overemphasized.
