Diarrhea vs Dysentery- Definition and 21 Major Differences

Diarrhea and dysentery are two common gastrointestinal disorders that affect millions of people around the world. They are both characterized by frequent and loose stools, but they have different causes, symptoms, and treatments. In this article, we will explain the differences between diarrhea and dysentery, and how to prevent and manage them.

Diarrhea and dysentery are both conditions that affect the digestive system and cause loose or watery stools. However, they have different causes, symptoms, and treatments. Here are some of the main differences between diarrhea and dysentery:

• Cause: Diarrhea can be caused by various factors, such as infections, food intolerance, medications, stress, or diseases of the intestines. Dysentery is usually caused by a specific type of infection by bacteria, parasites, or protozoa that invade the lining of the colon and cause inflammation and ulcers.
• Symptoms: Diarrhea typically causes frequent and urgent bowel movements, abdominal cramps, bloating, and dehydration. Dysentery causes more severe symptoms, such as bloody or mucus-filled stools, fever, nausea, severe pain in the abdomen or rectum, and dehydration. Dysentery can also lead to complications such as anemia, kidney failure, or sepsis if left untreated.
• Stool appearance: Diarrhea produces loose or watery stools that may vary in color and consistency depending on the cause. Dysentery produces stools that are often bloody or contain mucus or pus due to the damage to the colon. The stools may also have a foul smell and be accompanied by tenesmus (a feeling of incomplete evacuation).
• Treatment: Diarrhea can usually be treated at home with oral rehydration solutions (ORS) to prevent dehydration and electrolyte imbalance. Depending on the cause, diarrhea may also require dietary changes, probiotics, or medications to stop the diarrhea or treat the underlying infection. Dysentery requires medical attention and antibiotics to kill the causative agent and prevent further complications. In some cases, dysentery may also require amoebicidal drugs to eliminate the parasites from the body.

Diarrhea is a condition where a person has loose, watery stools more than three times a day. It can last for a few days or weeks, depending on the cause and severity. Diarrhea can be acute or chronic, and it can have various causes and complications.

Some of the common causes of diarrhea are:

• Infection by bacteria, viruses, parasites or other organisms that enter the digestive tract through contaminated food or water. Examples include E. coli, Salmonella, Campylobacter, Rotavirus, Norovirus, Giardia and Cryptosporidium.
• Food intolerance or allergy to certain foods that trigger an immune response or irritate the digestive lining. Examples include lactose intolerance, gluten intolerance, fructose malabsorption and celiac disease.
• Medications that affect the normal function of the intestines or increase the movement of fluids and electrolytes. Examples include antibiotics, antacids, laxatives, chemotherapy drugs and nonsteroidal anti-inflammatory drugs (NSAIDs).
• Diseases or disorders of the digestive system that impair the absorption of nutrients or cause inflammation or damage to the intestinal wall. Examples include inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), celiac disease, Crohn`s disease, ulcerative colitis and diverticulitis.
• Other conditions that affect the hormonal balance, metabolic rate or immune system of the body. Examples include diabetes, hyperthyroidism, HIV/AIDS, cancer and stress.

Some of the common complications of diarrhea are:

• Dehydration: This is the loss of water and electrolytes (such as sodium, potassium and chloride) from the body due to frequent and excessive stooling. Dehydration can cause symptoms such as thirst, dry mouth, reduced urine output, dark urine, dizziness, weakness, fatigue and headache. Severe dehydration can lead to low blood pressure, rapid heart rate, confusion, shock and even death.
• Malnutrition: This is the deficiency of essential nutrients (such as carbohydrates, proteins, fats, vitamins and minerals) from the body due to reduced intake or impaired absorption. Malnutrition can cause symptoms such as weight loss, muscle wasting, poor wound healing, anemia and increased susceptibility to infections. Severe malnutrition can lead to growth retardation, organ failure and death.
• Electrolyte imbalance: This is the disturbance of the normal levels of electrolytes in the blood due to excessive loss or inadequate replacement. Electrolyte imbalance can cause symptoms such as muscle cramps, twitching, numbness, tingling, irregular heartbeat and seizures. Severe electrolyte imbalance can lead to cardiac arrhythmia, coma and death.

Diarrhea can be diagnosed by a medical history, physical examination and stool tests. The treatment of diarrhea depends on the cause and severity of the condition. The main goals of treatment are to prevent dehydration and malnutrition by replacing fluids and electrolytes orally or intravenously; to treat the underlying infection or disease by using antibiotics or other medications; and to relieve symptoms by using antidiarrheal drugs or probiotics.

Diarrhea can be prevented by practicing good hygiene; washing hands before eating and after using the toilet; drinking safe water; avoiding raw or undercooked food; peeling or washing fruits and vegetables; storing food properly; avoiding food that causes intolerance or allergy; taking medications as prescribed; managing chronic conditions; and getting vaccinated against certain diseases that cause diarrhea.

Diarrhea is a common but potentially serious condition that affects millions of people worldwide. It can be caused by various factors and can have serious consequences if left untreated. Therefore, it is important to seek medical attention if diarrhea persists for more than two days; if it is accompanied by fever, blood in stool, severe pain or dehydration; or if it occurs in infants, elderly people or people with weakened immune systems.

Dysentery is an intestinal infection that causes severe diarrhea with blood or mucus. It may also cause abdominal pain, fever, nausea, vomiting, and dehydration. Dysentery can be caused by bacteria or parasites that infect the intestines, usually through contaminated food or water. The two most common types of dysentery are:

• Bacterial dysentery, also known as shigellosis, which is caused by bacteria from the genus Shigella. This is the most common type of dysentery in the United States, with about 500,000 cases diagnosed each year. Shigella bacteria can be spread by direct or indirect contact with feces of an infected person, such as through poor hand hygiene, shared food or utensils, or swimming in contaminated water. Shigella can also cause dysentery outbreaks in places where people are in close contact, such as day care centers, schools, nursing homes, or prisons.
• Amebic dysentery, also known as amebiasis, which is caused by a parasite called Entamoeba histolytica. This type of dysentery is less common in the developed world, but more prevalent in tropical areas with poor sanitation. Entamoeba histolytica can be ingested by eating or drinking contaminated food or water, or by swallowing cysts that are shed in the feces of an infected person. The parasite can invade the intestinal wall and cause ulcers and bleeding. It can also spread to other organs, such as the liver, and cause abscesses.

Dysentery can be diagnosed by a stool test that can identify the causative organism. Treatment depends on the type and severity of the infection. Mild cases may resolve on their own with adequate hydration and oral rehydration solutions. Severe cases may require antibiotics for bacterial dysentery or amoebicides for amebic dysentery. Complications of dysentery can include dehydration, liver abscess, post-infectious arthritis, hemolytic uremic syndrome, seizures, bloodstream infections, and death.

Dysentery can be prevented by practicing good hygiene and food safety measures, especially when traveling to areas where the infection is common. These include washing hands with soap and water regularly, especially after using the toilet; drinking only boiled or bottled water; avoiding raw or undercooked food; peeling fruits and vegetables before eating; and avoiding contact with feces of infected people.

One of the most noticeable differences between diarrhea and dysentery is the appearance of the stool. The stool is the solid or semi-solid waste material that is passed out of the body through the anus.

In diarrhea, the stool is usually loose, watery, and frequent. It may contain mucus, blood, or pus in some cases, depending on the cause of diarrhea. The color of the stool may vary from yellow to green to brown. The stool may also have a foul smell.

In dysentery, the stool is usually small, slimy, and bloody. It may contain mucus and pus as well. The color of the stool is usually red or black due to the presence of blood. The stool may also have a very offensive odor.

The difference in the stool between diarrhea and dysentery is mainly due to the different mechanisms of these conditions. Diarrhea is caused by increased intestinal motility and secretion of fluid and electrolytes into the lumen of the intestine. This results in a large volume of watery stool that is expelled frequently.

Dysentery is caused by inflammation and ulceration of the mucosa of the colon and rectum. This results in damage to the blood vessels and leakage of blood into the stool. The inflammation also causes mucus and pus production, which adds to the sliminess of the stool. The ulceration also reduces the capacity of the colon to hold fecal matter, resulting in small and frequent stools.

The comparison of stool in diarrhea and dysentery can help in diagnosing the condition and determining its severity. It can also guide the treatment and management of these conditions. For example, if the stool contains blood or pus, it indicates a bacterial or parasitic infection that may require antibiotics or amoebicidal drugs. If the stool is very watery and frequent, it indicates a risk of dehydration that may require oral rehydration solution (ORS) or intravenous fluids.

Diarrhea and dysentery are both conditions that cause frequent and watery stools, but they have different causes and treatments. Diarrhea is usually caused by viral or bacterial infections, food intolerance, medications, or other factors that irritate the digestive system. Dysentery is a more serious form of diarrhea that is caused by parasites or bacteria that invade the lining of the intestines and cause inflammation, bleeding, and mucus in the stools.

The main goal of treatment for both diarrhea and dysentery is to prevent dehydration, which can be life-threatening if left untreated. Dehydration occurs when the body loses more fluids and electrolytes than it can replace. Symptoms of dehydration include dry mouth, thirst, decreased urine output, dark urine, dizziness, weakness, and confusion.

The most effective way to prevent dehydration is to drink plenty of fluids that contain water, sugar, and salt. Oral rehydration solution (ORS) is a specially formulated drink that contains the right balance of these ingredients to help replenish the lost fluids and electrolytes. ORS packets are available over the counter in most pharmacies and can be mixed with clean water according to the instructions on the package. ORS should be given to anyone with diarrhea or dysentery as soon as possible and continued until the symptoms stop.

In addition to ORS, some over the counter medications can help reduce the frequency and severity of diarrhea or dysentery. However, these medications should not be used without consulting a doctor first, as they may have side effects or interactions with other drugs. Some of these medications are:

• Antidiarrheal drugs: These drugs work by slowing down the movement of the intestines and reducing the amount of water in the stools. Examples are loperamide (Imodium) and bismuth subsalicylate (Pepto-Bismol). These drugs should not be used for more than two days or if there is blood or mucus in the stools, as they may mask the symptoms of a more serious infection or cause complications.
• Antibiotics: These drugs kill or inhibit the growth of bacteria that cause diarrhea or dysentery. Examples are ciprofloxacin (Cipro), metronidazole (Flagyl), and azithromycin (Zithromax). These drugs should only be used if prescribed by a doctor after testing the stool for the specific type of bacteria or parasite. Antibiotics should be taken for the full course as directed by the doctor and should not be stopped or skipped even if the symptoms improve.
• Amoebicidal drugs: These drugs kill or inhibit the growth of amoebas, which are a type of parasite that cause amoebic dysentery. Examples are metronidazole (Flagyl), tinidazole (Tindamax), and paromomycin (Humatin). These drugs should only be used if prescribed by a doctor after testing the stool for amoebas. Amoebicidal drugs should be taken for the full course as directed by the doctor and should not be stopped or skipped even if the symptoms improve.

Diarrhea and dysentery are common but potentially serious conditions that require prompt and proper treatment. Over the counter medicines can help relieve some of the symptoms and prevent dehydration, but they should not replace medical advice or care. Anyone with diarrhea or dysentery should seek medical attention if they have any of the following signs:

• Severe abdominal pain or cramping
• Fever higher than 38°C (100.4°F)
• Blood or mucus in the stools
• Signs of dehydration
• Diarrhea or dysentery that lasts longer than two days
• Diarrhea or dysentery after traveling to a foreign country

Both diarrhea and dysentery can cause dehydration, which can be life-threatening if not treated promptly. Therefore, it is important to prevent and treat these conditions as soon as possible. Some of the common measures to prevent and treat diarrhea and dysentery are:

• Drink plenty of fluids, such as water, juice, soup, or oral rehydration solution (ORS), to replace the lost fluids and electrolytes. ORS can be bought from pharmacies or made at home by mixing 6 teaspoons of sugar and half a teaspoon of salt in 1 liter of clean water.
• Avoid caffeine, alcohol, dairy products, spicy foods, or foods that are high in fat or sugar, as they can worsen the symptoms or cause irritation to the digestive system.
• Eat small, frequent meals of bland foods, such as rice, bananas, toast, or crackers, to help restore the normal function of the intestines.
• Wash your hands frequently with soap and water, especially before eating or preparing food, after using the toilet or changing diapers, and after touching animals or their feces. This can help prevent the spread of infection and contamination.
• Use clean water for drinking and cooking, and boil or filter it if you are not sure about its quality. Avoid ice cubes or drinks made from tap water in areas where sanitation is poor.
• Peel or cook fruits and vegetables before eating them, and avoid raw or undercooked meat, eggs, seafood, or dairy products. These can harbor harmful bacteria or parasites that can cause diarrhea or dysentery.
• If you are traveling to a foreign country, especially in developing regions, consult your doctor about getting vaccinated against typhoid fever and cholera, which are common causes of dysentery. You may also need to take prophylactic antibiotics or antiparasitic drugs before or during your trip.
• If you have diarrhea or dysentery that lasts more than a few days, is severe or bloody, or is accompanied by fever, abdominal pain, vomiting, weight loss, or signs of dehydration, seek medical attention immediately. You may need to take antibiotics or antiparasitic drugs to treat the underlying infection. You may also need intravenous fluids or blood transfusions if you are severely dehydrated or anemic.

By following these preventive and treatment measures, you can reduce the risk of complications and recover faster from diarrhea or dysentery. Remember to stay hydrated and eat well-balanced meals to maintain your health and immunity.
