What are the important symptoms of uremia

summary

What are the important symptoms of uremia? The occurrence of uremia seriously damages everyone's spirit, torments everyone's health. If you want to avoid the harm of disease, you need to correctly grasp the important symptoms of uremia, and help everyone find their own treatment methods, so as to reduce the occurrence of disease harm.

What are the important symptoms of uremia

(1) metabolic acidosis: chronic renal failure, uric acid phase when the metabolic products of human acid such as phosphoric acid, sulfuric acid and other substances due to kidney excretion obstacles and retention, 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.

* (2) disturbance of water and sodium metabolism: mainly water and sodium retention, 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. On the other hand, when the patient has a lot of urine, and excessive water restriction, or complicated with vomiting, diarrhea and other gastrointestinal symptoms, it is easy to lead to dehydration. In clinical practice, excessive volume load is more common, so uremic patients should pay attention to the appropriate control of water intake (in addition to drinking water, but also including soup, porridge, fruit and other water rich food), in the process of diagnosis and treatment should avoid excessive fluid infusion, in order to prevent the occurrence of heart failure and pulmonary edema.

(3) Potassium metabolism disorder: when the GFR drops to 20-25ml / min or lower, the renal potassium excretion capacity gradually decreases, and hyperkalemia is prone to occur at this time; especially when excessive potassium intake, acidosis, infection, trauma, gastrointestinal bleeding and other conditions 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). Sometimes hypokalemia may occur due to insufficient potassium intake, excessive gastrointestinal loss, application of potassium excreting diuretics and other factors. Hyperkalemia is more common in clinic, so uremic patients should strictly limit the intake of high potassium food, and should regularly review blood potassium.

matters needing attention

We must understand the important symptoms of uremia. We all know that the occurrence of uremia seriously endangers our spirit. If we want to completely reduce the harm of disease, we must correctly grasp the important symptoms of uremia, and help you find targeted treatment plans, so as to avoid the occurrence of disease harm.
