What symptom is uremia?

summary

Uremia is not an independent disease, but a common clinical syndrome of many advanced renal diseases. It often occurs in the period of renal failure, and the renal function is on the verge of scrap. The clinical manifestations are disorder of metabolism of water and electrolyte in the body, imbalance of balance in the body, and the kidney is on the verge of scrap, Thus lead to toxins in the body, metabolic waste, not very good metabolism out, stay in the body, thus causing digestive tract, heart, lung, nervous system, muscle, skin and other systemic poisoning symptoms. What symptom is uremia? Next, I'd like to share my views with you.

What symptom is uremia?

* first: metabolic acidosis, chronic renal failure, uric acid metabolism, acid products such as phosphoric acid, sulfuric acid and other substances, due to kidney excretion obstacles, and can occur "uremic acidosis". In mild chronic acidosis, most patients have less symptoms, but if HCO3 in arterial blood is less than 15 mmol / L, obvious anorexia, vomiting, weakness, deep breathing and so on may appear.

* second: disturbance of water and sodium metabolism, mainly manifested as retention of water and sodium, or hypoxemia and hyponatremia. When the renal function is not complete, the ability of the kidney to adapt to excessive sodium load or volume gradually decreases. If the patients with uremia don't limit the water properly, it can lead to excessive volume load, common subcutaneous edema (eyelids, lower limbs) or / and body cavity effusion (pleural cavity, abdominal cavity). At this time, it is easy to have high blood pressure, left ventricular dysfunction (chest tightness, decreased activity tolerance and even can't lie flat at night) and brain edema.

Thirdly, the disorder of potassium metabolism: when the GFR decreased to 20-25ml / min or lower, the renal potassium excretion capacity gradually decreased, and hyperkalemia was prone to occur at this time; Especially when excessive potassium intake, acidosis, infection, trauma, gastrointestinal bleeding occur, hyperkalemia is more likely to occur. Severe hyperkalemia (serum potassium > 6.5 mmol / L) has certain risk and needs timely treatment and rescue (see the treatment of hyperkalemia).

matters needing attention

1. * no dietary protein should be consumed in the diet. When there are too many proteins in the body, nitrogen metabolism may cause certain obstacles and remain in the body, increasing the risk of uremia. 2. Try to keep away from the gases of chemicals that damage the kidney, such as chloroform, ethylene glycol and tetrachloroethylene. 3. Don't be greedy for appearance. Use some antique tableware during meals. The antique tableware is often coated with pigment containing a lot of cadmium.
