Hypokalemic periodic paralysis
Hypokalemic periodic paralysis is a muscle disorder characterized by recurrent episodes of flaccid paralysis of skeletal muscles and decreased serum potassium levels during attacks. It can be primary or secondary. This condition commonly affects individuals aged 20 to 40, with a higher incidence in males than females. The main symptoms include limb weakness and paralysis.
View detailsHyponatremia
Hyponatremia is a condition where the serum sodium concentration falls below the normal lower limit (135 mmol/L). It is relatively common clinically, especially in the elderly, and initial symptoms include fatigue, nausea, anorexia, dizziness, drowsiness, and apathy.
View detailsSimple goiter
The thyroid is a butterfly-shaped gland located in the neck. Patients with simple goiter have normal thyroid function, and it is characterized by an enlarged thyroid gland caused by iodine deficiency, goitrogenic substances, or genetic factors. It commonly occurs during puberty, pregnancy, lactation, and menopause, with the main manifestation being an enlarged thyroid gland.
Prolactinoma
Prolactinoma refers to a pituitary tumor that secretes excessive prolactin, leading to symptoms such as amenorrhea, galactorrhea, and infertility. It is commonly seen in young women aged 20-40, with a higher incidence in females than males. Prolactinomas can also occur in children and adolescents, but are relatively rare in the elderly.

Hyperosmolar hyperglycemic state (HHS), also known as hyperosmolar nonketotic diabetic coma, is a severe acute complication of diabetes characterized by hyperglycemia, hypernatremia, and high plasma osmolality, leading to severe dehydration (e.g., prostration) and altered consciousness (e.g., lethargy, confusion). It commonly affects individuals aged 50 to 70, predominantly those with type 2 diabetes, and occasionally type 1 diabetes. The onset of HHS is often insidious but progresses rapidly, with most patients presenting in a comatose or shock state (manifesting as pale skin and unconsciousness) at the time of diagnosis.
View detailsHyperphosphatemia
Hyperphosphatemia is a pathological condition characterized by an increase in phosphate levels in the blood above the normal range. Currently, a blood phosphate concentration exceeding 1.9 mmol/L (equivalent to 6 mg/dL) can be considered diagnostic of hyperphosphatemia. Hyperphosphatemia itself does not cause discomfort, but the underlying diseases that lead to elevated phosphate levels may present with symptoms. Additionally, severe hyperphosphatemia can be accompanied by hypocalcemia, leading to symptoms such as paresthesia, tetany, abdominal pain, nausea and vomiting, and impaired consciousness.
View detailsHyperkalemia
Potassium is one of the most important cations in the body. Its main physiological functions include maintaining cell metabolism, regulating osmotic pressure and acid-base balance, and playing an important role in maintaining the normal physiological functions of nerve and muscle cells. Hyperkalemia is a pathological condition characterized by a serum potassium concentration higher than 5.5 mmol/L, mainly caused by impaired renal function, excessive potassium intake, or the use of certain medications. Patients mainly present with muscle weakness, paralysis, and decreased myocardial contractility. In severe cases, it can lead to arrhythmias and cardiac arrest, and the electrocardiogram may also show specific abnormalities.
View detailsCretinism
Cretinism, also known as congenital hypothyroidism, is a condition caused by congenital factors leading to impaired synthesis and reduced secretion of thyroid hormones. This results in delayed growth and development, and intellectual disability in affected children. It is one of the most common endocrine diseases in pediatrics, with a male-to-female ratio of approximately 1:2.
