Some people are born with the inability to make the enzyme lactase. Others develop the intolerance over time. So, yes you could have developed this recently.
Symptoms of lactose intolerance generally begin within two hours of consuming milk or other dairy products. The severity of symptoms depends on how much lactase your body produces and how much lactose you eat.
Symptoms include:
Nausea
Cramping
Bloating
Abdominal rumbling sounds
Gas
Diarrhea
Loose stools
Diagnosis
The doctor will ask about your symptoms and medical history and perform a physical exam. Often he or she will recommend a two-week trial period of eating no milk or milk products. If symptoms subside, you will be asked to consume milk products again. If milk causes symptoms to recur, you will be diagnosed with lactose intolerance.
Your doctor may also order some tests, including:
Lactose tolerance test—measures the amount of glucose (simple sugar that is created from lactose) absorbed two hours after drinking a high-lactose liquid, indicating how well the body is digesting lactose
Hydrogen breath test—measures how much hydrogen is exhaled after drinking a high-lactose liquid
Stool acidity test—measures lactic acid in the stool for infants and small children
Biopsy of the small intestine—only performed in rare cases, this involves removing and testing a sample of tissue to confirm lactase deficiency
