Introduction
Common aftereffects following pesticide ingestion may include nervous system damage, gastrointestinal dysfunction, liver and kidney impairment, chronic respiratory problems, and blood system abnormalities. Some pesticides can damage neural tissues, leading to long-term headaches, dizziness, and memory decline; in severe cases, they may cause limb numbness, muscle tremors, and slowed reactions.

Common aftereffects that may occur following pesticide ingestion generally include nervous system damage, gastrointestinal dysfunction, liver and kidney impairment, chronic respiratory problems, and blood system abnormalities. A detailed analysis is as follows:

1. Nervous System Damage: This is a relatively common sequela. Some pesticides can damage neural tissues, leading to persistent headaches, dizziness, and memory decline. In severe cases, symptoms such as limb numbness, muscle tremors, slowed reactions, and even impaired speech or motor functions may occur. Recovery often requires a long rehabilitation period with ongoing therapy.

2. Gastrointestinal Dysfunction: Pesticides can irritate the mucous membranes of the stomach and intestines, causing prolonged digestive issues. These may include chronic abdominal pain, bloating, nausea, and vomiting, along with reduced appetite and indigestion. In serious cases, conditions such as chronic gastritis or intestinal adhesions may develop, impairing nutrient absorption.

3. Liver and Kidney Damage: The liver and kidneys are the primary organs responsible for metabolism and detoxification. Pesticide residues can increase their workload, resulting in long-term liver function abnormalities (e.g., elevated transaminase levels) and reduced kidney function (e.g., proteinuria). In severe instances, this may progress to chronic hepatitis or renal failure, requiring ongoing monitoring and treatment.

4. Chronic Respiratory Problems: Certain pesticides can damage the respiratory mucosa or lung tissue. This may trigger chronic bronchitis or asthma, manifesting as persistent cough, sputum production, chest tightness, and breathing difficulties. Reduced respiratory immunity increases susceptibility to recurrent infections.

5. Blood System Abnormalities: A few types of pesticides may affect blood components, leading to decreased white blood cell counts and low platelet levels. This can result in weakened immunity and a tendency to bleed easily (such as gum bleeding or skin bruising). In severe cases, coagulation function may be impaired, increasing the risk of hemorrhage.

If someone is found to have ingested pesticide, immediate medical attention is crucial—do not delay the optimal window for treatment. After treatment, regular follow-up tests including liver and kidney function assessments and complete blood counts are essential to monitor recovery progress.
