This signs may occur for a period of about 2 to 6 weeks. In some people, it may last longer.
Only see a doctor when you find you have a loose stool, abdominal bloating and nausea lasting more than a week, or when you also get dehydrated.
Inform your doctor if you suspect giardia infection and may have traveled to an endemic area in the recent past, or may have used water from a lake or stream.
Giardia infection is caused by a microscopic parasite which is found worldwide.
Giardia parasites live in the intestines of people and animals. However, before they passed in stool, they form a sheath as a case called cysts, this allows them to survive harsh intestinal and environmental conditions outside of the intestines for longer durations.
When they find themselves inside a host, the cyst dissolves and the parasite is released. The infection only occurs when you swallow the contaminated water from the stream or lake. Or contaminated food or through person to person contact.
The most common mechanism of getting infected with giardia is after swallowing contaminated water. Giardia parasites may be found in the lakes, ponds, rivers, and streams.
Municipal supplies, wells, cisterns and swimming pools and water, parks. Ground and surface water may also become contaminated from agricultural runoff, wastewater, discharge or animal fecal matter.
Person to person contact can be transmitting giardiasis when your hands become contaminated with fecal matter.
Parents changing diapers are also at risk.
Anal sex can also be the other way through which giardiasis can be infected.
4 Making a Diagnosis
Even after seeing your doctor, you still be referred to a gastroenterologist to receive a diagnosis of giardia infection since he is a specialist of the digestive disorders.
Before you visit your doctor, write down some of the answers to key pertinent questions such as:
When did your symptoms begin?
Is there anything that makes it better or worse?
Do you work with small children?
What types of medications do you use?
The doctor may also ask you to lie down so that you may be evaluated by gently pressing on the various parts of your abdomen to check for the tender areas.
Your mouth and skin may also be assessed for signs of dehydration.
You may be asked to come along with a sample of your stool for analysis and diagnosis of giardiasis. Several stool samples may be required for examination in the laboratory for presence of parasites. The stools can also be used for evaluation of the effectiveness of the treatment you receive.
Children and adults exposed to giardia infection and do not develop the symptoms may not require any form of treatment. They may get better on their own in a few weeks.
In case of severe signs and symptoms, or have persistent infection, the doctors may treat the giardiasis with medications such as Flagyl (metronidazole). It is a very common antibiotic for management of giardia infection.
It may however come with a few side effects such as nausea, metallc taste in the mouth. It is advised not to drink alcohol when using these drugs.
Tinidazole (Tindamax) works just like metronidazole, and have many of the similar side effects; it can be given as a single dose.
Nitazoxanide (Alinia) is developed in a liquid form and is believed to be the easier form for the children. Some of the side effects may include nausea, flatulence, yellow eyes and very brightly colored urine.
However, there is no specific recommendation for the management of giardiasis more especially during pregnancy since the drugs have potential adverse effects on the baby. However, if the symptoms are mild, it may be recommended that the treatment be delayed until after the first trimester. When the treatment is available, you may assess the best treatment option with you doctor.
