The most intensive development of the child occurs in the prenatal period and during its first year of life.
Newborns have some characteristics for weight gain, since they have, during the first week of life, a physiological loss of body weight.
What is this physiological loss or loss of body weight in a newborn and what is it connected to? Here are the frequently asked questions that concern young mummies.
Let’s talk about this in more detail.
Weight gain in newborns
The initial body weight loss in newborns is mainly due to the small starvation in the first days of life (since milk in mom is beginning to arrive) and due to the imperceptible loss of water through respiration and sweat. The excretion of urine, meconium, the fall of the umbilical cord, are also attributed to the causes of weight loss of the newborn.
The physiological decrease in body weight is observed in all newborns and does not depend on body weight at birth.
The maximum decrease in the child’s initial body weight usually falls in 3-5 days. Measure it as a percentage in relation to body weight at birth.
Factors that contribute to great values of maximum body weight loss:
- Great body weight at birth (more than 4 kg)
- Birth injury
- Prolonged work
- Maternal hypogalactia
- High temperature in the room for a newborn
- Insufficient humidity in the room for a newborn.
The smallest values of physiological loss of body weight are usually:
- In the girls
- In children with clinical manifestations of hormonal crisis.
- In children born during repeated birth
- Attached to the mother’s breast in the first 2 hours of life.
- In newborns who are in the “free feeding”.
Degree – with a weight loss of less than 6%. With this degree of clinical manifestations of dehydration no. There may be some greed in sucking.
But in the laboratory indicators there may be signs of intracellular hypohydration (dehydration). This is an increase in the concentration of sodium in plasma, potassium in erythrocytes, high values of the potassium-nitrogen ratio of the urine. But, as a rule, in healthy newborns, these figures do not determine, therefore, these changes in the body go unnoticed.
Do not worry, as they do not affect the health of the baby.
Grade II – with a weight loss of 6-10%. The clinical manifestations may be absent or the child is thirsty, anxious, irritable crying. Other symptoms are the brightness of the mucous membranes, the slow unfolding of the skin fold, the tachycardia, the difficulty in breathing.
Laboratory data indicate intracellular and extracellular hypohydration: an increase in the value of the hematocrit, total serum protein, oliguria (decrease in the amount of urine), an increase in the relative density of the urine.
Grade III – weight loss of more than 10%. Clinically, the child is thirsty, severe dryness of mucous membranes and skin, the fold of the skin is softening very slowly, large springs of spring, tachycardia, shortness of breath, there may be an increase in body temperature , anxiety and tremor.
In some children, on the contrary, adynamia (decreased motor activity), decreased reflexes, until its complete extinction, marbling of the skin is observed. Laboratory data indicate pronounced signs of intracellular and extracellular hypohydration: a significant increase in blood sodium levels, blood clots (increase in hematocrit), and an increase in total plasma protein.
Oliguria is also observed and an increase in the relative density of the urine.
Prevention of dehydration with physiological loss of body weight.
Rational organization of newborn care and breastfeeding. – Early chest closure with posterior lock every 2-2.5 hours (or free feeding mode)
Temperature conditions (Do not let the child overheat)
With the appearance of clinical manifestations, with a daily loss of body weight greater than 4%, with the child overheated, with the identification of signs of dehydration in the laboratory, it is advisable. add baby between feeding 5% glucose (or 5% glucose in half with Ringer’s solution).
Recovery of body weight in the newborn.
After a transient (physiological) loss, recovery of body weight at birth in healthy newborns usually occurs at 6-7 days of age. In some children, the necessary increase in body weight may be delayed until the second week of life.
In premature babies, especially in those with grade 3-4, as well as in children with high birth weight, the recovery of body weight occurs more slowly.
The baby’s weight gain per month
The rate of weight gain for a newborn in the first month of life is an average of 600 grams.
In addition, respectively, the weight gain per month is as follows
2 months – 800 grams
3 months – 800 grams
4 months – 750 grams
5 months – 700 grams
6 months – 650 grams
7 months – 600 grams
8 months – 550 grams
9 months – 500 grams
10 months – 450 grams
11 months – 400 grams
12 months – 350 grams
The baby’s weight at 11-12 months of life increases approximately 3 times. In a one-year-old baby, on average, weighs 10-11 kg.
