Hi, I had gone through your question and understand your concerns. Normally, urine that contains a lot of water has little to no odor. If your baby s urine becomes highly concentrated and very yellow — a high level of waste products with little water — urine odor may have a strong ammonia smell. Many foods and medications, such as lots of chocolate,peas,beans or certain vitamins, can affect the odor of urine. Sometimes, unusual urine odor may indicate a medical condition or disease, such as: -Urine tract infection -Dehydration -Diabetic ketoacidosis (high levels of blood acids called ketones) -Gastrointestinal dysbiosis, which lead to increase of uric acid and ketoacidosis -Maple syrup urine disease (rare genetic disease that causes difficulty breaking down certain amino acids) -Metabolic disorder If I were your treating Doctor for this case I would suggest: 1. Keep your baby hydrated with plenty of water or ORS. 2.Hypouricosuric diet-avoid products, enriched with uric acid(spinach,beets,radish,chocolate,peas). 3.For better digestion I advise my patients to take Enzyme s syrup. 4. Also take probiotics group of medicines like as Darolac, Visilac 1 capsule once a day for normal flora of intestine. Start on these changes and get back to me in 2 to 3 months. Wish you and your son good health.
