Brief Answer:
Hello Welcome XXXX!
Detailed Answer:
To answer your question, most definitely Nuvaring may be involved in your excessive weight gain. The effects on weight and appetite are individual, increasing or decreasing weight depending on the individual's metabolism, diet and lifestyle habits.
This is the same for all oral contraceptives, the effects may vary depending on who is taking them.
It is thought that oral contraceptives increase insulin resistance which may affect how nutrients are metabolized. It is suggested that the following nutrients be increased when taking these contraceptives: magnesium, folic acid, riboflavin and pyridoxine although I usually have my symptomatic patients take 100 mg of magnesium and a B-complex pill. This is not to say it will solve the weight gain problem.
Since edema may often be a problem and part of the weight gain, I generally ask my clients to restrict their sodium in their diet to 2300 mg/day, but to keep hydrated with 8-10 glasses of water per day.
In conclusion, to answer your question, Nuvaring may be the cause or significant factor in your sudden weight gain.
Yours in good health, XXXXXXX J. Shattler, MS,RDN
