Why does the baby suddenly reduce urination?

Question 1: My baby is one year old. He still urinates very little after drinking tea in the past three days. If he doesn’t drink tea, his urine will be yellow. But if he drinks tea, his urine will be clearer. He doesn’t urinate as much as before. In the past, he could urinate a few times by drinking 90 ml of warm water. I\’ve peed twice now, and I feel a little uncomfortable. I vomited once the night before yesterday, and I had four bowel movements yesterday morning. I had urinary bowel movements, and I haven\’t had any bowel movements since the afternoon. What\’s going on? I am also afraid that if I drink fake milk powder, it will cause kidney stones in my child. I have been worried all day long. What tests should I do? Dr. Cui Lixia answered: Vomiting and defecation will cause decreased urination. Today you can check your urine routine. If you are worried, you can draw blood to check your kidney function. Kidney stones can be confirmed by B-ultrasound examination. The two tests are different. Blood draws are used to check kidney function to see if kidney function is damaged. B-ultrasound is used to check for kidney stones. The presence of kidney stones does not necessarily mean kidney damage. Question 2: My baby is six months old and has a clear nose. It has been running for three months. Before, the flow was less every day. I went to the hospital and the doctor said it was fine and no need to take medicine. Today, the flow is heavy and it keeps sneezing. What should I eat? Medicine? Dr. Luo Zhen’s answer: Apply a warm towel to the baby’s nose, use a nasal aspirator to suck out the mucus in time, spray physiological sea salt water nasal spray, there is no limit to the number of sprays, and take children’s Jiegan granules and cetirizine drops , one-third pack of Jiegan granules three times a day, and cetirizine drops 0.25 ml each time, twice a day. Question 3: I am now 37 days postpartum. On the 20th day of confinement, I started to bleed a little every other day. Today I went for a checkup and it was said that there is pathological pelvic effusion, and the vagina is sometimes itchy. What should I do? Dr. Pan Guilan’s answer: Pay attention to rest. Normally, the uterus returns to normal size 42 days after delivery. It is normal to still have bleeding. Pathological pelvic effusion is mainly caused by inflammation. You can take some anti-inflammatory drugs orally. Check if it is itchy. It\’s not the use of sanitary napkins that causes infection. Make sure your perineum is clean and dry, and wash it with warm water.
