It's eleven at night and your six-year-old is awake and crying again. She keeps scratching her bottom, tosses around in bed and shows up at school the next morning with dark circles under her eyes. Grandma already called it at dinner: "that girl has worms." She may be right, or not. Intestinal parasites are common in children from every neighborhood, Spring Branch included, and they say nothing about how clean your home is. What does matter is confirming them properly and treating them in a way that keeps them from returning a week later.
The parasites children pick up most often
Not every gut "bug" is the same. Each one spreads differently and causes different trouble, so it helps to know them by name.
| Parasite | How it reaches the child | The telltale clue |
|---|---|---|
| Pinworms | Eggs carried from fingernails to the mouth, or from bedding and toys | Itching around the anus, mostly at night |
| Giardia | Untreated water, pools, unwashed hands at daycare | Foul-smelling diarrhea, gas, a bloated belly |
| Roundworm (Ascaris) | Contaminated soil, poorly washed fruit and vegetables | Belly pain, low appetite, sometimes a visible worm in the stool |
| Amoebas and other protozoa | Contaminated water or food, often while traveling | Diarrhea that comes and goes, sometimes with mucus |
Pinworms are by far the most common in school-age kids. At night a female worm crawls out to lay eggs on the skin around the anus. That causes the itch, the child scratches, eggs lodge under the fingernails and travel from there to the mouth, the backpack or a little brother's hand. That's why they tend to move from one child to the whole household.
Clues you may notice at home
Plenty of children with parasites have no symptoms at all. When there are some, these show up most:
- Itching around the anus or, in girls, irritation of the vaginal area, worse once they lie down.
- Restless sleep: waking up, kicking, never quite resting.
- Recurring belly pain around the navel.
- Diarrhea lasting days, very smelly or greasy stools, lots of gas.
- A poor appetite, or a child who isn't gaining weight like classmates.
- A tiny white worm, thin as a thread, in the underwear or the stool.
If you spot something in the stool, don't just flush it: a phone photo gives the medical team a real head start.
Family wisdom versus the evidence
Some beliefs get handed down for generations, and they're worth sorting from the facts:
"Candy gives kids worms." Sugar doesn't create parasites. What spreads them are eggs that reach the mouth through hands, water or contaminated food.
"He grinds his teeth, so it must be worms." Teeth grinding is common in children and nearly always has other causes, such as tiredness or tension. It can't diagnose parasites.
"Everyone should get dewormed every so often, just in case." Giving an antiparasitic without knowing which parasite is there may miss the one the child actually has and delays the diagnosis. Teas, raw garlic on an empty stomach and seeds haven't been shown to clear parasites either. Confirm first, treat second.
How it's confirmed: the stool test
At our Gessner Rd clinic we run the stool test for children and adults. The lab looks through the sample for parasite eggs or forms, signs of bacterial infection and leftovers suggesting food isn't being digested well; when the history points that way, the medical team adds an occult blood test. You get the container and instructions during the visit, and the sample is collected at home.
One useful detail about pinworms: since they lay their eggs outside the body, on the skin, they don't always appear in a stool sample. As general information, the CDC describes a test using clear adhesive tape pressed against the skin around the anus first thing in the morning, before bathing. That's why it matters to tell the medical team about the nighttime itching even if the sample comes back clean.
Collecting a child's sample without a battle
Getting a stool sample from a little one is awkward and a bit funny, but with some planning it works on the first try:
- Set up the bathroom first. Lay plastic wrap loosely across the toilet bowl, or use a clean potty chair if your child still uses one, so the stool never lands in the water.
- Keep urine out of it. Ask your child to pee first, then sit down for the rest.
- For kids in diapers, scoop the sample straight from the diaper with the spoon in the lid, from a spot that isn't wet.
- A little is plenty: about the size of a walnut. If you see mucus or anything that looks like a worm, include it.
- Close it tightly and label it with your child's name and the time you collected it.
- Bring it in soon. If you can't leave right away, put it in a bag in the fridge, never the freezer.
If the result is positive
Treatment depends on which parasite turns up, and the medical team decides it based on the child's age and weight. Don't reach for medicine left over from a cousin or one suggested over the phone. When a prescription is needed, it's sent electronically to the pharmacy you choose, as our e-prescription page explains, and before you leave we tell you how to give it and whether it should be repeated.
With pinworms, everyone living in the home is often treated at the same time, because a single untreated person can pass them right back to the rest. Alongside the medicine, these habits break the cycle:
- Short, clean fingernails, and no nail biting or finger sucking.
- Handwashing with soap after the bathroom, before eating and when kids get home from school.
- A morning shower to wash off eggs laid on the skin overnight.
- Clean underwear or pajamas every day.
- Sheets, towels and pajamas washed in hot water, without shaking them out first so eggs don't scatter.
- Well-washed fruit and vegetables, and safe drinking water, especially when the family travels.
When parasites linger for months
Left untreated, some parasites slowly rob a child of nutrients and iron. A pale, very tired child, or one who is small for their age, may also need a complete blood count; the clinic's blood tests show whether anemia is present. If the school physical or sports physical is coming up, it's a good moment to bring up weight, appetite and sleep as well.
When a tummy problem can't wait for a clinic visit
Parasites are rarely an emergency, but diarrhea and belly pain sometimes are. Any of these means the ER or a 911 call, not a wait for a clinic slot:
- Stools that are tar-black or carry plenty of red blood.
- Few or no bathroom trips or wet diapers for many hours, crying with no tears, dry lips, or a floppy child who is hard to rouse.
- Strong, constant belly pain, especially low on the right side or with a hard belly.
- Vomiting that won't stop, or green vomit.
- A high fever along with looking very unwell.
A visit in Spring Branch that fits your day
If your household has gone several nights without sleep because of the itching, or your child's tummy ache keeps coming back every week, stop by Clínica Hispana Nueva Salud Gessner on Gessner Rd (77080). We're open every day until 9 PM, so you can come after school pickup or after work, walk in or call ahead, and take the container home from that same visit. Without insurance, you can pay for the visit directly. Write down when the itching started, whether anyone else at home is scratching and, if you took one, bring the photo of what showed up in the stool.
