Cancerous kidney tumor. This representation details the
development of malignant cells in the adult renal system. The text
addresses main symptoms such as hematuria and abdominal
pain. It also presents the genetic and environmental risk factors
that influence the overall prognosis
Cancerous prostate is a common malignant tumor in older men
caused by uncontrolled prostate cell growth. Moreover, it may cause
urinary symptoms and spread to other organs. Diagnosis includes PSA
testing and biopsy, while treatment depends on stage and progression.
Celiac intestinal disease: an autoimmune disorder where gluten
causes atrophy of the small intestine villi. This prevents nutrient
absorption and generates fatigue, diarrhea, and weight loss. The only
effective treatment is a lifelong gluten-free diet.
Cortisol production occurs in the adrenal cortex after
ACTH stimulation from the pituitary. It regulates
metabolism, blood pressure, and the body’s response
to stress.
Cortisol secretion occurs in the adrenal cortex after
stimulation by ACTH from the pituitary. It regulates
metabolism, blood glucose, and the stress response
through the endocrine axis.
Deficient hemoglobin: an anemic condition where the blood has
few red blood cells or low protein concentration. This reduces the
capacity to transport oxygen to tissues, causing fatigue and pallor.
It requires a medical diagnosis and nutritional
Demyelinating multiple sclerosis is an autoimmune disease where
the immune system damages the myelin sheath of nerve fibers. This
process disrupts brain signals, causing movement issues, sensitivity
problems, and chronic neurological symptoms.
Dermatomyositis and muscle weakness: an autoimmune
disorder where inflammation damages tissues and reduces muscle
mass. It causes severe motor weakness and progressive atrophy.
Treatment combines immunosuppressive drugs and specialized
physical therapy.
Diabetes mellitus type 1: an autoimmune disease where the pancreas
does not produce insulin. The body cannot process glucose, raising sugar
in the bloodstream. It requires the use of daily pumps or injections,
mainly affecting children and young people in their metabolic development.
A diabetic person feels low. This realistic illustration analyzes
the biological scenario of insulin resistance. The content explains
how cells respond inefficiently, forcing the pancreas to overwork,
leading to type 2 diabetes under factors like a sedentary lifestyle.
Diffuse thyroid goiter defines the uniform enlargement of the
thyroid gland, frequently caused by a lack of iodine. This condition
alters hormonal production, causing fatigue, weight gain, and
visible swelling in the neck area.
Dryness in Sjögren’s syndrome is an autoimmune condition
where the immune system attacks the lacrimal and salivary glands.
This pathology reduces moisture in the eyes and face, causing
persistent irritation, a foreign body sensation, and generalized skin dryness.
