Fertility Treatment & Diet


Do you know about the metabolic syndrome?  Recently, we often see or hear about it in magazines and on television.  It’s talking about the fat attached to internal organs that becomes the cause to lifestyle related diseases such as diabetes, high blood pressure, and arteriosclerosis.  One might think that this is just “a story for middle-aged over-weight men”.  But even in the case of a young woman, it has been made clear that obesity is a cause of menstrual irregularities.

 The fat cells make a protein called adiponectin, but this protein is helping the action of insulin.  However, once one becomes fat, we found that the secretion of adiponectin from the enlarged fat cells is reduced, leading to hardening of the arteries.  In a recent study as well, we have found that when adiponectin is reduced in obesity, the ovary’s skin becomes thick, the egg may not grow well and it will become difficult to ovulate.  In conclusion, obesity is the cause of “menstrual irregularities” and “infertility”.





Therefore, in our hospital, we will recommend a diet first to those with ovulation disorder accompanied by obesity.  Additionally, even if you get pregnant as obese, it is trouble.  You cannot diet while pregnant.  However, fat still attached to the birth canal will lead to dystocia (difficult birth).  For example, even if a cesarean section is done, if the fat is thick the wound will not heal well, and complications such as thrombosis is likely to occur. 
You become infertile by obesity, and even if you get pregnant and let’s assume the risk is high, well then what is best way to diet?  We cannot recommend your own self-made diet.   This is because in a self-made diet, just as there is a lack of the necessary nutrients causing rough skin, even if you lose weight it is often that rather the state of ovulation will worsen. 

It is very easy to say with words that it is a healthy diet.  “I will stop snacking, have a well balanced meal that fills only 80% of my stomach, and everyday I’ll walk the one train stop’s distance….”  If you do it like this, you will most certainly lose weight.  However, we all know that in actuality it will not last long. 

In fact, as well as medically we have found things like the following.  The fat cells secrete a hormone called leptin that increases energy consumption and suppresses the appetite.  However, obesity weakens the function of leptin.  Because of this, appetite cannot be suppressed, energy consumption decreases becoming a vicious cycle.  Additionally, depending on the type of gene, there are also bodies that are predisposed to gaining weight.   

That is why a medically-prescribed program is necessary, even if for a short time, in order to healthily lose weight.  In our hospital we have developed a treatment program (Oak Diet) under medical supervision, which will deliver safe results in a short-term.  In the Oak Diet, it is made from low calories and one hardly notices the feeling of hunger and moreover, doesn’t lack any necessary nutrients.  So, it’s a diet that can produce results rather easily so to speak.  To describe the short period of time, it will take 2 months to align with the maintenance period and the rapid weight loss period, but in the meantime it is suppressed in the rebound and you will ideally lose weight.  Rather than one’s self-made diet, after weight is controlled with a medical diet treatment like this, then it is recommended to receive treatment for infertility.



【Real Example】

Patient A was admitted with infertility.  She already had problems with ovulation, her menstrual cycle was irregular and she only had one period in a time of half of a year to a year.  At the time of her first examination her last period was one year ago.  She was well obese at 165 cm tall, weighing 81.5 kg, her waist line at 106 cm.  For that, we first started her on the Oak Diet, and after two months we had successful weight loss of 14 kg, making her 67.5 kg.  Soon her ovulation was restored to normal, and then she naturally got pregnant.
