Gastrointestinal issues encompass a range of digestive symptoms including nausea, vomiting, abdominal pain, constipation, and diarrhea. These symptoms can be caused by infections, dietary factors, medications, nutritional deficiencies, or toxic exposures such as lead poisoning. The Lead Blood Test is the most important test for identifying lead toxicity as an underlying cause of persistent gastrointestinal symptoms.

Gastrointestinal issues are caused by a variety of factors including bacterial or viral infections, food poisoning, medication side effects, dietary intolerances, stress, inflammatory bowel conditions, and toxic exposures like lead poisoning. Common infectious causes include bacteria such as Salmonella, E. coli, and Helicobacter pylori, or viruses like norovirus and rotavirus. Environmental toxins, particularly lead exposure from old paint or contaminated water, can also trigger significant digestive symptoms including nausea, vomiting, abdominal cramping, and constipation.
The Lead Blood Test is the most important test for gastrointestinal issues when toxic exposure is suspected because it detects elevated lead levels that cause constipation, nausea, vomiting, and severe abdominal pain. This test is essential for identifying lead poisoning, which can mimic other digestive disorders and requires immediate intervention to prevent neurological and organ damage. While gastrointestinal issues often require clinical evaluation and stool tests for infections, blood testing for lead is crucial when symptoms persist without clear cause, especially in individuals with potential occupational or environmental lead exposure such as construction workers, painters, or those living in older homes.
You should get tested if you experience persistent or severe digestive symptoms such as ongoing abdominal pain, unexplained nausea and vomiting lasting more than a few days, sudden changes in bowel habits like chronic constipation or diarrhea, blood in your stool, or unexplained weight loss. Testing is especially important if you have potential lead exposure through your job, live in a home built before 1978, or have children showing similar symptoms. You should seek immediate testing if your symptoms are accompanied by fever, severe dehydration, or if you work in industries involving metal work, battery manufacturing, or renovation of old buildings.

What this means
Your blood lead level is slightly elevated above the reference range. While this is not immediately dangerous, it indicates you have been exposed to lead from your environment, and continued exposure could lead to more serious health effects over time. Identifying and eliminating the source of lead exposure is important to prevent accumulation.
Recommended actions
Inspect your home for peeling paint, contaminated dust, or old plumbing and have your water tested
Increase intake of calcium, iron, and vitamin C-rich foods to reduce lead absorption
Practice good hygiene by washing hands before eating and using wet mops for cleaning
Retest in 1-3 months after removing exposure sources to monitor improvement
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
