Giardia Infection (Giardiasis)

Giardia is a common intestinal infection. It's caused by tiny parasites that live in the environment. These parasites can be found almost anywhere, but are more likely to be present in areas with poor sanitation and unsafe water sources.

Giardia, also known as giardiasis, is a significant problem, especially in the United States. It's often spread through contaminated water. This can include natural sources like streams and lakes, as well as public water systems, swimming pools, hot tubs, and even wells. The parasites can also spread through food and when people come into contact with an infected person.

Symptoms of giardia infection usually include stomach aches, feeling full or bloated, queasiness, and diarrhea. The diarrhea is often watery. Most people recover from giardia within a few weeks. However, some people may experience lingering intestinal issues even after the infection is gone.

Fortunately, there are medicines that can treat giardia. These medications are often effective, but not everyone responds to them. The best way to avoid getting giardia is through prevention.

Giardia is a parasite that can cause infection. Sometimes, people infected with giardia don't show any noticeable symptoms. However, they can still pass the parasite to others through their stool. If you do get sick, you'll likely start noticing symptoms between one and three weeks after you were exposed.

These symptoms can include:

• Loose, sometimes smelly stools: Your bowel movements might be watery, or sometimes they might be soft and have a greasy appearance. They may even alternate between these types.
• Feeling tired: You might experience general fatigue.
• Stomach discomfort: This can include cramping or a feeling of fullness and bloating in your stomach.
• Gas: You might have more gas than usual.
• Upset stomach: This can manifest as nausea, a feeling of wanting to vomit.
• Weight loss: In some cases, giardia infection can lead to unintentional weight loss.

These symptoms usually last between two and six weeks. However, some people experience them for longer periods or have them come back again later.

If you have diarrhea, stomach pain, swelling, and feeling sick to your stomach that lasts more than a week, call your doctor. Also, call if you're getting dehydrated.

Tell your doctor if you might have gotten giardia. This is important if you have a child who attends daycare, have recently been in an area where giardia is common, or if you've drunk water from a lake or stream. Giardia is a type of parasite that can cause these symptoms.

Giardia are tiny parasites that live in the intestines of humans and animals. Before they leave the body in stool, these parasites form protective, hard coverings called cysts. These cysts are tough and can survive outside the body for a long time, sometimes even for months. When the cysts get inside a new host, they break open, releasing the parasites.

You get infected with Giardia when you accidentally swallow these cysts. This can happen in several ways. One common way is by drinking contaminated water. Eating food that has been handled by someone who has Giardia can also cause infection. Finally, close contact with someone who is infected can spread the parasites.

Giardia is a common parasite that affects the intestines. While anyone can get it, some groups are more likely to be infected.

Children are particularly vulnerable. Giardia is much more common in kids than adults. This is because kids often come into contact with contaminated materials, like feces. Diapers, potty training, and time spent at daycare increase the risk. Parents and caregivers who spend time with young children also face a higher chance of getting giardia.

People with limited access to clean water are also at higher risk. Areas with poor sanitation and unsafe drinking water are hotbeds for giardia infections. If you travel to regions where giardia is prevalent, it's crucial to be cautious about what you eat and drink, especially if the water isn't bottled or treated. Rural areas and wilderness settings often pose the biggest risks.

People who engage in unprotected anal sex are at increased risk. Individuals who participate in anal sex or oral-anal sex without using condoms or other protective measures are more susceptible to giardia, as well as other sexually transmitted infections (STIs). This is because giardia can be spread through bodily fluids exchanged during these activities.

Giardia infection is rarely deadly in developed countries. However, it can cause problems that last for a while, especially in young children. These problems can include:

• Dehydration: Giardia often causes diarrhea, which can lead to dehydration. This happens when the body loses too much water, making it hard for the body to work properly. Symptoms of dehydration include feeling dizzy, lightheaded, or having dry mouth and skin. In severe cases, dehydration can be very serious and may require medical attention.

• Poor growth and development (failure to thrive): If a child has giardia and chronic diarrhea, they may not be able to get enough nutrients. This can lead to malnutrition and problems with their physical and mental growth. These children might not gain weight or develop normally, affecting their overall health and well-being.

• Milk sugar intolerance (lactose intolerance): Some people who get giardia develop a temporary or even lasting inability to digest milk sugar (lactose). This means they might have stomach upset after drinking milk or eating dairy products. This problem can continue even after the giardia infection goes away. Symptoms might include bloating, gas, diarrhea, and stomach cramps.

There's no medicine to stop giardia infection. However, following some simple steps can greatly reduce your risk of getting it or spreading it.

Handwashing is Key: Washing your hands is the most effective way to prevent many infections, including giardia. Thoroughly scrub your hands with soap and water for at least 20 seconds after using the restroom, changing diapers, or before eating or preparing food. If soap and water aren't available, use an alcohol-based hand sanitizer. Important Note: Alcohol sanitizers aren't as good at killing the giardia cysts that can live in the environment.

Safe Water is Crucial: Don't drink untreated water from natural sources like lakes, rivers, streams, springs, or shallow wells without purifying it. Always boil water for at least 10 minutes at a rolling boil (158°F or 70°C) or use a reliable water filter.

Food Safety Matters: Thoroughly wash all raw fruits and vegetables with clean water before eating them. For extra safety, peel fruits if possible. If you're traveling to areas where water quality might be questionable, be cautious about eating raw produce.

Protect Yourself When Swimming: Avoid swallowing water while swimming in lakes, rivers, or pools.

Bottled Water for Travel: When visiting places with potentially unsafe water supplies, stick to bottled water. Make sure you open the bottle yourself to avoid contamination. Avoid using ice made from potentially contaminated water.

Safe Sex Practices: If you practice anal sex, always use a condom. Avoid oral-anal contact unless you use a condom to prevent transmission.

To find out if you have giardiasis (a giardia infection), your doctor will likely want to test a sample of your stool. For the most accurate results, you might need to provide several stool samples over a few days. A lab will look at these samples to see if any giardia parasites are present. These stool tests can also help your doctor see if the treatment you're getting is working.

Many people get giardia, a parasite infection, without any noticeable symptoms. If you don't have symptoms, you probably don't need treatment unless you might spread the infection to others. Most people with mild giardia get better on their own within a few weeks.

However, if your symptoms are severe or don't go away, a doctor might prescribe medication.

Important Note: There isn't a single best treatment for giardia during pregnancy. This is because some medications could potentially harm the developing baby. If you're pregnant and have giardia, talk to your doctor. They can help you decide what's best for you and your baby, possibly recommending waiting until after the first trimester or even longer if your symptoms are mild. If treatment is needed, you should discuss the safest and most effective options with your doctor.

Common medications used to treat giardia include:

• Metronidazole (Flagyl): This is a common antibiotic used to treat giardia. Possible side effects include feeling sick to your stomach and a metallic taste in your mouth. It's very important not to drink alcohol while taking this medication.

• Tinidazole (Tindamax): This medication works similarly to metronidazole but can often be taken in a single dose. Potential side effects are similar to metronidazole.

• Nitazoxanide (Alinia): This medicine is sometimes easier for children to take because it's available as a liquid. Possible side effects include feeling sick to your stomach, gas, and yellowing of the eyes and urine.
