Chemical poisoning can occur when the body comes into contact with a toxic substance. According to MayoClinic.com, chemical poisoning can occur through inhalation or swallowing. It can also result when the skin, eyes or mucous membranes are introduced to a toxic substance. Knowing the symptoms and signs of chemical poisoning can ensure rapid treatment of the poisoning. However, symptoms of chemical poisoning often resemble symptoms of other conditions such as stroke and seizure. People who suspect chemical poisoning should contact a poison control center or seek emergency medical attention.
Mild Poisoning
A mild chemical poisoning can result in joint soreness and chronic headaches. According to MayoClinic.com, there may also be nausea, diarrhea, fatigue and irritation of the skin and eyes. Since chemical poisoning frequently affects the digestive system, weight loss and decreased appetite are common with a mild chemical poisoning. Perspiration, restlessness and weakness typically occur from chemical poisoning because of the body's inability to defend itself against the toxic substance.
Moderate Poisoning
Severe diarrhea and stomach cramps are symptoms of moderate chemical poisoning, reports the Centers for Disease Control and Prevention. Muscle coordination may decrease, and muscles may occasionally twitch or spasm. As with mild chemical poisoning, eye irritation, skin irritation, blurred vision and excessive saliva are other symptoms of moderate poisoning. As moderate chemical poisoning progresses and the substance spreads to more organs and tissues, other symptoms may include excessive perspiration, trembling and moodiness. Most patients with moderate chemical poisoning experience breathing difficulties, rapid pulse and skin that appears yellowed or flush.
Severe Poisoning
Intense thirst is the most reported symptom of those with severe chemical poisoning, states the Centers for Disease Control and Prevention. This occurs because certain chemicals force the body to perspire and lose body fluids, which causes dehydration. Additional symptoms include an increased breathing rate, uncontrollable muscle spasms and tremors, and smaller eye pupils. In certain severe chemical poisoning cases, the nails often display discoloration or turn yellow as the substance leaves traces there. If treatment is not rendered, the inability to breathe or unconsciousness can ensue.
