Why amino acid injections are not recommended

Generally, it is not recommended to use amino acid injection arbitrarily, as there are concerns about potential side effects and risks associated with improper use, such as allergic reactions, nutritional imbalances, liver dysfunction, kidney damage, and metabolic acidosis. If in doubt, decisions should be made under the guidance of a qualified physician. Specific analyses are as follows:

1. Allergic reactions: Amino acid injections may contain certain components such as preservatives or excipients, which could trigger immune responses in sensitive individuals, leading to allergic symptoms including rash, itching, and difficulty breathing.

2. Nutritional imbalance: Although amino acid injections provide essential amino acids, they may not meet all nutritional requirements. Long-term reliance on a single source of nutrition can lead to nutritional imbalances and impair bodily functions, manifesting as weakened immunity, dry skin, and muscle weakness.

3. Liver function impairment: In patients with pre-existing liver damage, excessive amino acids cannot be effectively metabolized, potentially accumulating and producing toxic substances such as ammonia. This increases the burden on the liver and may even trigger hepatic encephalopathy, presenting symptoms such as jaundice, ascites, and confusion.

4. Kidney injury: Excess amino acid metabolites must be excreted through the kidneys. In cases of renal insufficiency, these metabolites may accumulate in the body, leading to azotemia and electrolyte disturbances, thereby further damaging kidney function. Symptoms may include edema, hypertension, and reduced urine output.

5. Metabolic acidosis: The metabolism of amino acids produces acidic byproducts. Under normal conditions, the body's buffering systems maintain acid-base balance. However, when amino acids are administered in excess or in the presence of metabolic disorders, the accumulation of acidic metabolites may exceed the buffering capacity, resulting in acidosis. Symptoms include rapid breathing, increased heart rate, and fatigue.

The decision to use amino acid injections should be based on a thorough assessment of the patient’s specific condition and clinical status, and must be made under the supervision of the attending physician.
