However the main function of the small intestine is the absorption of the small food particles resulting from digestion. It contains many villi which increase the surface area for absorption.

Respiratory failure caused by botulism can result in death. About 50 years ago half of all patients with botulism died, compared to just 8% today. Patients with severe symptoms may need a breathing machine, intensive medical and nursing care for several months. Fatigue and shortness of breath may linger for many years.
When paralysis reaches the chest, death from inability to breathe results unless the patient is ventilated. Symptoms of botulism generally appear 12 to 72 hours after eating contaminated food. With treatment, illness lasts from 1 to 10 days. Full recovery from botulism poisoning can take weeks to months. Some people never fully recover. In general, symptoms of botulism poisoning include the following: 1  Nausea. 2  Vomiting. 3  Fatigue. 4  Dizziness. 5  Double vision. 6  Dry skin, mouth and throat. 7  Drooping eyelids. 8  Difficulty swallowing. 9  Slurred speech.
