What is the reason that I gained 4 kilograms for 2 weeks with Yaz tablets?

When using Yaz, weight gain is possible, but is an uncommon side effect - it occurs in 1 to 10 for every 1000 people. The increase in body weight by as much as 4 kilograms in two weeks is large, but if you have not observed weight problems before, it is difficult to clearly associate it with the fact of skipping a placebo, which in some cases is acceptable. According to the information about the drug: "Although not recommended, you can delay the onset of withdrawal bleeding by skipping the white placebo tablets from the 4th order and moving directly to the second blister of Yaz until its end. When using tablets from the second blister, spotting or mid-cycle bleeding may occur. Discontinue the second pack with 4 white placebo tablets from the 4th row of the second pack. Then you should start using the tablets from the next blister. You can consult your doctor before deciding to delay the onset of bleeding." I would suggest that you first consider whether the measurement was made in a reliable way, both before and now - on the same weight, at about the same time of day, without clothes or, possibly, in clothing that does not contribute in its weight to the differences. You can also try to assess whether there are swellings that could contribute to an increase in the measurement result. If the weight continues to increase or you notice other disturbing signals, it will be advisable to contact your doctor.
