Time of the Month: Sugar Cravings, Uncomfortable Bloating, and the Dreaded Weight Gain!

While you might associate your period with these unpleasant symptoms, the menstrual cycle is actually a very important female hormonal process.

A woman’s period occurs on average once per month, and its purpose is to prepare the body for possible pregnancy— or to prevent her from wearing white for a week.

Let’s take a closer look at the four phases in the menstrual cycle:

Menstruation or Period LadyThis is what most women would call their ‘period’ as it is when the initial bleeding takes place.

The body rids itself of the thickened lining which has built up in the uterus, producing blood from the lining cells.

Sanitary pads and tampons are used during this stage to absorb blood flow, and if you’re out of those, a nappy will do the trick.

  • Follicular phase-

During this phase, a hormone is released which signals to the ovary to produce follicles, the growth of these follicles causes an increase in the hormone estrogen.

Although up to 20 follicles are produced, each with the potential to develop into an egg, only one will.

The lining of the uterus thickens in preparation in case the egg is fertilized to prepare the body for pregnancy (this a whole other story, best to ask your parents).

  • Ovulation-

As mentioned previously, only one egg develops from the follicles and during ovulation, the ovary releases this mature egg.

The rise in estrogen from the follicular phase causes a knock on hormonal effect whereby other hormones are released in response to one another, and in a conversation-like manner (think Twitter), they work together to eventually trigger the ovulation process.

The egg is pushed down the fallopian tube and stays alive for approximately 24 hours before it is fertilized by a sperm, or dies (sob)!

  • Luteal phase-

Although the egg is released during ovulation, the follicle remains on the ovary and morphs into a hormone-releasing structure that produces progesterone and estrogen, which help the thickened lining of the uterus stay intact.

If an egg is fertilized, then this structure continues to produce the necessary hormones for pregnancy, but if fertilization does not occur then progesterone levels fall and the uterus lining falls with it to repeat the cycle of menstruation (oh joy)!

Pre Menstrual Syndrome

While the period plays an important role in the women’s health, it can also be the cause of several unpleasant symptoms which many women experience in the week or so leading up to menstruation.

These symptoms collectively are known as PMS, pre-menstrual syndrome, or “don’t talk to me, I’m on my period”.

A study, published by Ulrike Schmidt in 2013 found that up to 75 percent of women experience symptoms of premenstrual syndrome including fatigue, low energy and anxiety.

The study also concluded that approximately 10 percent of women experienced a very severe form of PMS known as premenstrual dysphoric disorder.

Other PMS Symptoms include:

  • Sugar cravings (must have chocolate)
  • Mood swings and depression (no really, I’m FINE)
  • Period pains (touch me and you die)
  • Weight gain (I feel like a whale)

Weight Gain 

Watch Your Weight Gaining TimeThe hormone progesterone, which is elevated during the luteal phase right before your period begins, can be known to contribute to PMS weight gain in the form of gas, constipation, diarrhea, and the slowing of digestion— all of which can cause bloating and water retention.

These symptoms can cause food to sit in the digestive tract for longer than usual and thus increase scale weight temporarily.

Hormonal changes can also affect the balance of water in the body and many women experience edema in the week before their period starts, which can add up to 5lbs of scale weight— yikes!

It is often thought that fluid retention is at its highest in the week leading up to the period and that scale weight begins to drop as soon as bleeding occurs.

A study published in 2011 by Colin P. White discovered that after testing the fluid retention levels of 62 women during the stages of the menstrual cycle over the span of one year, edema was actually at its highest on day one of menstruation.

This is something to keep I mind if you step on the scales regularly, as weighing yourself both before and during your period can be disheartening and highly inaccurate.

Use calipers to measure your body fat for a more consistent and concise way to track body composition.

Top Tips To Minimize Weight Gain

  1. Drink Water

The body is made of up to 60% water.

Water nourishes your cells and keeps you hydrated.

Slight dehydration can cause a retention of water, so by ensuring that you are consuming enough H2O, you’ll look and feel your best.

Water helps to improve digestion which will further avoid added edema during the week before your period— and water fills you up so it can prevent you from overeating.

  1. Reduce Salt

Salt attracts water, and by consuming high sodium foods you are actively encouraging fluid retention.

Opt for pink Himalayan salt, which is unprocessed, full of minerals and in addition to sodium, it contains other electrolytes such as potassium and magnesium (unlike white table salt) which will help to balance the water in your body.

  1. Wear Loose Clothing

Feel comfortable during this uncomfortable time by wearing loose-fitting clothing if you are experiencing any bloating or fluid retention.

Avoid restricting waistbands too as they can affect the efficiency of your digestive system, forget fashion for a week and your body will thank you for it!

  1. Choose Carbohydrates Wisely

High sugar carbohydrates and white starches can not only bloat, but they can also encourage your body to hold more water— which is the last thing you need during time of the month!

High fiber whole grain carbs such as brown rice can assist in good digestion, keep you feeling fuller for longer and reduce cravings for high sugar foods.

A study published in 2016 found that a woman’s appetite typically increases during the luteal phase, which is the period right before your period (see what I did there)?

  1. Exercise

Exercise may be the last thing you feel like doing, but by moving and stretching you are releasing the tension in your body, allowing your digestive system to work more efficiently, promoting healthy blood flow (which can reduce cramps) and minimizing weight and fluid gain— winning!

In a 12 week study, it was found that regular exercise significantly reduced PMS associated symptoms and that aerobic exercise in particular, dramatically improved depression linked to premenstrual syndrome.

If you enjoy cardio, then yoga, cycling, and swimming are great pre-period exercise options.

Performing circuit style bodyweight exercises can also be a great way to incorporate both cardio and resistance workouts into your training regime before your period begins— and both forms of exercise can effectively help to alleviate many of the PMS symptoms you might experience before menstruation.
