What is the reason that human body lacks potassium

summary

The severity of clinical manifestations of potassium deficiency depends on the degree of intracellular and extracellular potassium deficiency and the rate of occurrence of potassium deficiency. The symptoms of acute hypokalemia are more severe than those of chronic hypokalemia with the same level of potassium deficiency. Let's take a look at the following.

What is the reason that human body lacks potassium

First, the common symptoms of neuromuscular system are myasthenia and paroxysmal soft paralysis, the latter can have myasthenia before attack. Although the seizure is related to the absolute level of plasma [k], it is more closely related to the intracellular and extracellular [k] gradient. The greater the gradient, the greater the difference between resting potential and threshold potential, resulting in the decrease of muscle excitability. Paralysis may also occur when plasma [k] is elevated. The most common muscle involved was the limbs. The head and neck muscles were not involved, but the respiratory muscles were involved and dyspnea occurred.

Second: can also have painful spasm or hand and foot convulsions. Most of the central nervous system is normal, conscious, and may have mental symptoms such as apathy, depression, sleepiness, memory and disorientation, etc. The superficial nerve reflex was weakened or disappeared completely, but the deep tendon reflex and abdominal wall reflex were less affected.

Third: before the attack can have numbness of limbs, and then fatigue, finally autonomic activities completely disappeared. Generally, the symptoms of proximal muscles are milder than those of distal muscles. Patients can not stand, walk, sit or squat can not stand up, lighter reliable hand support reluctantly stand up, sleep in bed can not turn over.

matters needing attention

The lack of potassium in digestive system can slow down the intestinal peristalsis. The patients with mild potassium deficiency had only anorexia, abdominal distension, nausea and constipation; Severe potassium deficiency can cause paralytic ileus.
