To diagnose botulism, your doctor will check you for signs of muscle weakness or paralysis, such as drooping eyelids and a weak voice. Your doctor will also ask about the foods you've eaten in the past few days, and ask if you may have been exposed to the bacteria through a wound.
In cases of possible infant botulism, the doctor may ask if the child has eaten honey recently and has had constipation or sluggishness.
Analysis of blood, stool or vomit for evidence of the toxin may help confirm an infant or foodborne botulism diagnosis. But because these tests may take days, your doctor's exam is the main way to diagnose botulism.
For cases of foodborne botulism, doctors sometimes clear out the digestive system by inducing vomiting and giving medications to induce bowel movements. If you have botulism in a wound, a doctor may need to remove infected tissue surgically.
If you're diagnosed early with foodborne or wound botulism, injected antitoxin reduces the risk of complications. The antitoxin attaches itself to toxin that's still circulating in your bloodstream and keeps it from harming your nerves.
The antitoxin cannot, however, reverse the damage that's been done. Fortunately, nerves do regenerate. Many people recover fully, but it may take months and extended rehabilitation therapy.
A different type of antitoxin, known as botulism immune globulin, is used to treat infants.
Antibiotics are recommended for the treatment of wound botulism. However, these medications are not advised for other types of botulism because they can speed up the release of toxins.
If you're having trouble breathing, you'll probably need a mechanical ventilator for as long as several weeks as the effects of the toxin gradually lessen. The ventilator forces air into your lungs through a tube inserted in your airway through your nose or mouth.
As you recover, you may also need therapy to improve your speech, swallowing and other functions affected by the disease.
Preparing for your appointment
You may first see your primary care doctor. However, you'll likely be sent to the hospital for immediate treatment. At the hospital, you'll probably see several doctors, including those who specialize in neurology (neurologist) and infectious diseases.
What you can do
- Bring any medications you take with you, and let your doctor know about any vitamins or supplements you're taking.
- Write down questions to ask your doctor. Although you may not have time to write down questions before your first appointment, write down any questions you want to ask at your follow-up appointments.
For botulism, some basic questions to ask your doctor include:
- How did I get botulism?
- Will I have any lasting problems?
- What side effects can I expect from treatment?
- Are there dietary restrictions I need to follow?
- How can I prevent this from happening again?
Don't hesitate to ask your doctor any other appropriate questions.
What to expect from your doctor
Your doctor is likely to ask you a number of questions, such as:
- When did you begin having symptoms?
- Have your symptoms been continuous or occasional?
- Have you or your child eaten any home-canned food recently?
- If your infant is ill, has he or she consumed honey?
- Did anyone else eat the food suspected of making you ill?
