Conditions Flashcards
Type 1 diabetes
Aka: juvenile diabetes or insulin dependent diabetes
-Body’s immune system destroys insulin producing cells in the pancreas.
-Chronic condition
-Occurs in childhood/adolescence
-Pancreas makes little to no insulin.
-S/S:
Thirsty
Frequent urination
Hunger
Loss of weight unintentionally
Irritable mood swings
Blurred vision
Type 2 diabetes
-AKA: Adult onset diabetes, obese diabetes.
-Pancreas does not produce enough insulin to keep blood sugar levels within a healthy range.
-Cells in muscle, fat and liver become resistant to insulin->cells don’t make enough sugar.
-S/S:
Thirsty
Hungry
Fatigue
Blurred vision
Diabetic neuropathy
Slow healing sores
Malaria
-Disease caused by a parasite-> mosquito
-infects the liver—> blood cells—>mosquito bites and transmits.
S/S:
Fever
Chills/Shivering
Diarrhea
Muscle and joint px
Tachycardia
Cellulitis
-Bacterial skin infection
-Occurs when a break in the skin allows bacteria to enter.
-if left untreated it can spread to lymph nodes( life threatening)
-MC in the lower leg
-S/S:
Swollen
Expanding
Warm
Blister
Hyperthyroidism
Primary:
-Over production of thyroid hormone by thyroid gland.(thyrotoxytocis)
Secondary :
-Thyroid is overproducing due to TSH(d/t hypothalamus or pituitary overproduction)
S/S:
-Anxiety/irritability
-weight loss
-fatigue
-tachycardia w palpitations
-sexual dysfunction
-frequently loose stools
-thinning of hair
-goiter
Graves’ disease
Graves’ disease: mimic TSH which binds to TSH receptor antibodies- stimulating increased thyroid gland production.
-Exopthalamus (bulged eyed d/t Graves.
S/s:
-exopthalamus
-goiter
-pretibial myxedema(fat nodules)
- unintentional weight loss
-erectile dysfunction
-change in menstrual function
Hypothyroidism
Underactive thyroid:
-causes:
-MC form hashimotos thyroditis a autoimmune condition attacks thyroid gland.
-Iodine deficiency.
-treatment for hyperthyroidism can lead to hypothyroidism.
S/S:
-Dry skin
-Coarse hair/hair loss
-weight gain
- amenorrhea(period stops unexpectedly)

-constipation
-fatigue/muscle ache
-depression
Check:
Tsh levels or high
T4 and T3
Hyperparathyroidism
4 glands posterior
-Produce PTH when there are low levels of calcium in blood.
-when PTH is released it increases absorption of Ca2+ from intestines, kidneys and increases osteoclastic activity.
Causes:
Tumor
Low Vit D
Hyperplasia
S/S:
Fatigue
Depression
Polyuria
Constipation
Cushing’s syndrome
When there is an increase in cortisol-> alarms ACTH(adrenocorticotrophic hormone) and CRH(corticotrophin releasing hormone) to stop production of cortisol.
Excessive cortisol s/s:
-Lowers immune system
-Inhibits bone formation
-Raises blood glucose
-Increases metabolism
-Increases alertness
Causes of Cushings;
-too much steroids
-Cushings disease- pituitary adenoma producing acth-> excessive cortisol.
-adrenal Cushings-d/t adenoma
S/S:

-Bilateral hilar lymphadenopathy-dry cough and dyspnoea
Other:

-Caused by atherosclerosis reducing blood flow to the myocardium.
-during exercise there is a high demand of blood supply being constricted.
-Relieved by rest!
Pericarditis
Inflammation of the pericardium.
Patho:
Pericardium is the lubricating sac around the hear to prevent friction.

Ps:
ARBs are recommended if person does not tolerate ACE inhibitors d/t dry cough. These should not be used together.
Thiazide diuretic are used as an alternative if the patient does not tolerate calcium channel blockers due to Odema.
