DIGESTIVE SYSTEM

Abdominal Pain

The acronym ABDOMINAL can help you to assess the cause of abdominal pains.

Associated symptoms: what other symptoms are present, e.g., nausea, vomiting, fever, weakness, headache?

Blood: is there blood in the stool or vomit? How much? What color is it (red or darker)?

Description: what does the pain feel like? Is it sharp or dull, constant or intermittent, localized or general, is it getting worse?

Onset: when did the pain start? Was it gradual or sudden? What makes it feel better (or worse)?

Menstruation: is it a female patient? Could her menstruation cycle have anything to do with it? Could she be pregnant?

Inspection: inspect the abdomen with palpation. Is there any tenderness?

Nutrition: this includes food and hydration. What’s gone in? What’s come out?

Auscultation: what sounds are his/her bowels making? Must Read – Secondary Exam - Physical Exam – Full Body Exam (Abdomen).

Losing volume: is the patient vomiting? Does the patient have diarrhea? If so, how much?

Diarrhea and Dysentery

Diarrhea

Diarrhea is when you get frequent loose, watery stool.

Traveler’s diarrhea can last up to a week.

Identify and treat/prevent the cause.

Monitor and treat to prevent dehydration; Diagnoses and Treatments – Circulatory System – Dehydration and Volume Shock – Dehydration.

Rehydration plan; Diagnoses and Treatments – Circulatory System – Dehydration and Volume Shock – Rehydration Plan.

Pharmaceuticals:

It is best to just let diarrhea pass, but if you need to slow the symptoms, these medications can help:

Anti-fever.

Antisecretory: Pepto-Bismal every hour, max 20/day.

Loperamide: Imodium, 4mg initial dose then 2 mg every 4 hours, max 16 mg/day.

Antibiotic for cholera: ciprofloxacin 1 g orally once, as an adjunct to fluid and electrolyte replacement.

Antibiotic for cholera: doxycycline 200 mg on the first day, given in 2 divided doses followed by 100 mg per day or 100 mg orally every 12 hours for severe cases.

Specific medications for dysentery depend on the type, i.e., amoebic or bacillary. The diagnosis of these is usually made in a lab with stool samples.

If there is no advanced medical care available, and the dysentery does not self-resolve, a combination of an amoebicidal drug (to kill parasites) and an antibiotic (to treat bacterial infection) may help, e.g., ampicillin (antibiotic) 500 mg every 6 hours and metronidazole (systemic amoebicide) 750 mg 3 times a day for 5 to 10 days.

Alternative/Natural Remedies for Diarrhea and Dysentery in General:

Brown rice water. Boil brown rice in double the amount of water with a pinch of salt. Strain and drink. the water.

Tea every 2 to 3 hours: chamomile (strong), garlic and honey, peppermint, plantain seeds, tannin (strong for dysentery, will taste terrible), ginger tea will decrease any abdominal cramps.

For severe cases when nothing else is available:

Bones: burn then grind them into a powder. Swallow the powder.

Chalk: consume school chalk

Activated charcoal is preferable. If that is unavailable, mix tea and wood charcoal (not briquettes) and add milk of magnesia if available.

Diverticulitis

Diverticulitis is a common intestinal infection, usually in people over 40. Pouches can form inside the lining of the colon, known as diverticula. When these pouches fill with feces, it can lead to infection.

Symptoms of Diverticulitis

Prevention of Diverticulitis

High fiber diet.

Regular bowel movements.

Food Poisoning

Food poisoning or food-borne illness is when infectious organisms (bacteria, viruses and parasites) or their toxins are consumed.

Symptoms of Food Poisoning

Confusion.

Dizziness.

Nausea.

Palpitations.

Vision disturbances.

Vomiting.

Treatment for Food Poisoning

Wash your mouth out as soon as possible.

Make yourself vomit either with 2 fingers down your throat or Ipecac. When using Ipecac, only use the smallest amount that will cause you to vomit.

Pharmaceutical:

Hydrocortisone cream.

Specific soothing creams, e.g., Anusol.

Stool softeners to decrease further trauma.

For severe cases the clot may need to be removed:

If advanced medical care is not available, a simple incision can be made to relieve pressure. This will not remove the hemorrhoid completely and it may come back.

Clean the area thoroughly with antiseptic.

Use local anesthesia if available.

Incise the skin over the hemorrhoid and drain the clotted blood; only cut as deep as you have to in order to drain the blood.

Relief should come very quickly.

Be prepared to absorb any bleeding, e.g., gauze pads.

Clean and dress.

Hepatitis

Hepatitis is when the liver becomes inflamed. This impairs the body’s ability to do many important things, including processing toxins. Hepatitis can result in death.

Treatment for Nausea and Vomiting

Fresh air.

Treat the cause.

Pharmaceuticals:

Anti-vomiting medication, e.g., ondansetron (Zofran).

Dimenhydrinate (Dramamine) for motion sickness: 50 to 100 mg every 4 to 6 hours, to a maximum of 400 mg in 24 hours, the first dose should be taken 30 to 60 minutes before starting activity.

Alternative/Natural Remedies:

Clove oil: diffused clove oil is good for morning sickness. One drop on the roof of the mouth may help any nausea.

Ginger: most useful for motion sickness. Candied ginger is good to keep handy when traveling.

Peptic Ulcer

Peptic ulcers (stomach ulcers) are painful sores in the lining of the stomach. There are a variety of causes, including NSAIDs.

Prevention of Peptic Ulcers

Eating four or five small meals a day.

Avoid alcohol, carbonated beverages, coffee, fruit juice and milk.

Salmonella, Typhoid Fever and Paratyphoid Fever

Salmonella is a type of food poisoning which can cause typhoid fever, paratyphoid fever and salmonellosis. The most common foods affected are beef, eggs, milk and poultry, but anything has the potential to be infected and will often show no signs of contamination.

Apart from poorly handled food, salmonella can also be transmitted via drinks and animal feces (especially that of baby birds), rodents, reptiles or any pet that has diarrhea. Be sure to wash your hands after being in contact with any of these types of animals.

Symptoms of Salmonellosis

Abdominal cramps.

Diarrhea.

Fever.

Treatment for Salmonellosis

Salmonellosis usually subsides within a week.

Treat symptoms.

Monitor for dehydration; Diagnoses and Treatments - Circulatory System - Dehydration and Volume Shock - Dehydration.

Pharmaceuticals:

Antibiotic: ciprofloxacin, 500 mg every 12 hours for 10 days.

Typhoid/Paratyphoid Fever

Typhoid fever is caused by either the salmonella typhi or paratyphi bacteria. For practical purposes, consider paratyphoid a less serious version of typhoid fever.

Regions of highest risk are Chile, India, Mexico, Pakistan, Peru, Southeast Asia and Sub-Saharan Africa.

Relapses may occur after a week or two and are more common in those that take antibiotics. Relapses are treated in the same manner.

Antibiotic: ciprofloxacin 500 mg every 12 hours for 10 days.

Antibiotics (other): ampicillin, azithromycin.

Prevention of Salmonella, Typhoid Fever and Paratyphoid Fever

Apart from general good hygiene, the following precautions can be taken:
