Final answer:
In lactose intolerant individuals, undigested lactose leads to the production of gas and short-chain fatty acids, causing abdominal cramps, bloating, and diarrhea. Galactosemia is another condition tied to lactose metabolism, resulting in the accumulation of galactose, with potentially serious health impacts. Additionally, tremetol poisoning from consuming affected milk can cause vomiting, pain, and tremors.
Step-by-step explanation:
Some toxic metabolites that could cause symptoms in people with lactose intolerance include gases like hydrogen, carbon dioxide, and methane, which are produced during the fermentation of undigested lactose by bacteria in the large intestine. This process also leads to the formation of short-chain fatty acids and lactic acid. As a result, symptoms such as abdominal cramps, bloating, diarrhea, and sometimes even nausea and vomiting can occur. These symptoms tend to cease once the lactose is eliminated from the body through feces.
In case of galactosemia, the inability to metabolize galactose properly due to the deficiency of the enzyme galactose-1-phosphate uridyl transferase leads to the accumulation of galactose, causing severe symptoms like diarrhea, vomiting, and can result in more serious complications if not managed with a lactose-free diet.
Furthermore, there's a phenomenon known as "milk poisoning" or tremetol poisoning which is unrelated to lactose intolerance but is caused by the consumption of milk from cows or goats that have ingested the white snakeroot plant, containing tremetol, a metabolic poison. This can lead to symptoms such as vomiting, abdominal pain, and tremors, worsened by physical exertion due to impaired lactate metabolism in humans.
