Lifestyle and diet might help you manage semelhantes à TPM symptoms, but it is unrealistic to expect these changes to get rid of your symptoms completely.

Dr Karen Morton, Founder and Medical Director, Dr Karen's Women's Health Service Ltd, suggests first getting to the root of your menstrual health issues.

"The hormones oestrogen and progesterone can be blamed for most symptoms," she explains. "Oestrogen dominates in the first half of your menstrual cycle and progesterone in the second. It's the progesterone which causes gut bloating and bowel changes, together with a bit of fluid retention and spottiness."

For many patients who experience troublesome PMS symptoms, she recommends using the pílula anticoncepcional combinada back to back to eradicate your period altogether. Having a Mirena coil or similar Sistema intrauterino (SIU) fitted may have the same effect, although irregular bleeding can be an issue, especially in the early months.

How your lifestyle can help

Morton admits that maintaining a healthy lifestyle and keeping active can help with premenstrual symptoms.

"Of course exercício and diet are the key to every aspect of our health, and this applies to PMS as well," she says. "Boosting exercise at that time of the month will boost endorphins, which are your body's own morphine, and also other brain agents which enhance mood.

"Being kind to yourself and practising mindfulness are also strongly recommended. Talking to friends and loved ones about how you are feeling rather than bottling it up ready for an explosion is a good idea."

Nutritional therapist Jackie Lynch, WellWellWell Nutritional Therapy believes maintaining healthy blood sugar levels is crucial for managing PMS symptoms.

"When your blood sugar drops, you feel tired, irritable, shaky, headachy - all of which can be PMS symptoms," she explains. "Every time your blood sugar drops, you're going to be more prone to sugar cravings because stress hormones are released and they will encourage your body to release sugar stores from your liver. This generates a big craving via your brain for sugar to redress the balance."

The stress hormones released can have a big impact on your cycle, she continues.

"Cortisol is the one that generates cravings. But if you're constantly releasing adrenaline, because your blood sugar drops or because you're under long-term estresse generally, then that's going to prevent your body from being able to use progesterone properly in the second half of your cycle."

Lynch recommends foods containing magnesium for those experiencing PMS because of its all-round benefits. Dietary sources of magnesium include dark green leafy vegetables such as spinach, broccoli and wholegrain foods.

She says: "It can really help when you're feeling jittery and anxious because one of the things that it does is calm your nervous system and help regulate your body's response to stress, keeping you feeling on top of things."

Magnesium also regulates muscle function.

"That's not just the obvious muscles that you might think of but, for example, the muscle in your gut," she explains. "Magnesium stimulates peristalsis. Peristalsis is the contraction and relaxation of the gut as it pushes food through. Quite often before your period, you might find yourself a bit constipado and bloated. Magnesium makes sure you're more regular."

Magnesium can also help ease the pain of PMS-related headaches.

"It helps to relax your blood vessels as well and if you're low in magnesium, that can often cause them to go into spasm," says Lynch. "It's one of the main causes of menstrual headaches."

B vitamins could be especially useful in improving low mood caused by PMS.

"Low levels of B vitamins - in particular B6 - have a strong association with anxiety and depression, whether it's PMS-related or not," explains Lynch.

If your PMS is causing you to feel suicidal or attempt self-harm, it is critical that you speak with a health professional immediately. This could be a symptom of premenstrual dysphoric disorder (PMDD) or part of a wider mental health issue.

Persistent low mood, depressão, ansiedade, feelings of helplessness, low self-esteem and trouble sleeping are also cause for a visit to your doctor. It's important to make them aware if these symptoms only occur or worsen during certain phases of your menstrual cycle.
