Pre­mens­tru­al syn­dro­me (PMS) includes phy­si­cal and psy­cho­lo­gi­cal sym­ptoms that recur in the time befo­re mens­trua­ti­on and subs­i­de again once blee­ding beg­ins. The seve­ri­ty of sym­ptoms varies wide­ly. If PMS affects your dai­ly life or well­be­ing, tar­ge­ted assess­ment and an indi­vi­du­al­ly tail­o­red tre­at­ment plan may be advi­sa­ble. On this page, you can find out more about sym­ptoms, dia­gno­sis and tre­at­ment opti­ons for PMS.

What is PMS?

Pre­mens­tru­al syn­dro­me (PMS) refers to recur­ring phy­si­cal and psy­cho­lo­gi­cal sym­ptoms that occur in the second half of the cycle and subs­i­de again when mens­trua­ti­on beg­ins or short­ly after­wards. The­se may include, for exam­p­le, irri­ta­bi­li­ty, mood swings, low mood, breast ten­der­ness, flu­id reten­ti­on, fati­gue or pain.

The exact cau­ses are not ful­ly unders­tood. One suspec­ted fac­tor is increased sen­si­ti­vi­ty to the nor­mal hor­mo­n­al chan­ges during the mens­tru­al cycle.

What can I do mys­elf to reli­e­ve PMS sym­ptoms?

For mil­der sym­ptoms, regu­lar exer­cise, suf­fi­ci­ent sleep and stress-reduc­tion mea­su­res can be hel­pful. Rela­xa­ti­on tech­ni­ques such as pro­gres­si­ve mus­cle rela­xa­ti­on can also sup­port well­be­ing. Avo­i­ding nico­ti­ne and being mindful with alco­hol and caf­feine may also be advi­sa­ble.

Diet and cer­tain die­ta­ry sup­ple­ments are also being stu­di­ed in con­nec­tion with PMS. For some mea­su­res, the­re are indi­ca­ti­ons of a pos­si­ble effect, but the evi­dence varies depen­ding on the pro­duct. Die­ta­ry sup­ple­ments should the­r­e­fo­re not be used across the board, but sel­ec­ted indi­vi­du­al­ly as nee­ded.

How is PMS trea­ted?

Tre­at­ment depends on which sym­ptoms occur, how seve­re they are and how much they affect dai­ly life. Seve­ral mea­su­res are often com­bi­ned.

For phy­si­cal sym­ptoms such as pain, pain­kil­lers may be used, for exam­p­le. For pro­no­un­ced psy­cho­lo­gi­cal sym­ptoms or pre­mens­tru­al dys­pho­ric dis­or­der (PMDD), sel­ec­ti­ve sero­to­nin reupt­ake inhi­bi­tors (SSRIs) can be an effec­ti­ve tre­at­ment opti­on. Depen­ding on the medi­ca­ti­on and indi­vi­du­al situa­ti­on, they may be taken con­ti­nuous­ly or for a limi­t­ed peri­od during the second half of the cycle.

Com­bi­ned hor­mo­n­al con­tracep­ti­ves can also redu­ce pre­mens­tru­al sym­ptoms in some women. We will dis­cuss which tre­at­ment is appro­pria­te on an indi­vi­du­al basis, taking into account your sym­ptoms, pos­si­ble risk fac­tors and any desi­re to have child­ren.

In addi­ti­on, mea­su­res such as exer­cise, stress reduc­tion and psy­cho­the­ra­peu­tic approa­ches such as cogni­ti­ve beha­viou­ral the­ra­py may be bene­fi­ci­al.

Do I have PMS?

Typi­cal sym­ptoms in the second half of the cycle include:

  • Breast ten­der­ness
  • Flu­id reten­ti­on
  • Fati­gue or sleep dis­tur­ban­ces
  • Mood swings, irri­ta­bi­li­ty or low mood
  • Head, back or lower abdo­mi­nal pain
  • Dif­fi­cul­ty con­cen­t­ra­ting

A sym­ptom dia­ry can pro­vi­de important clues. For at least two mens­tru­al cycles, note which sym­ptoms occur, how seve­re they are and when they subs­i­de again. Typi­cal of PMS is a recur­ring pat­tern in the second half of the cycle with a clear impro­ve­ment during or short­ly after the onset of mens­trua­ti­on.

During the medi­cal con­sul­ta­ti­on, we will cla­ri­fy your sym­ptoms and their timing in rela­ti­on to your cycle. If nee­ded, fur­ther exami­na­ti­ons may be useful to rule out other pos­si­ble cau­ses. Blood or hor­mo­ne tests are the­r­e­fo­re used sel­ec­tively when your medi­cal histo­ry or sym­ptoms indi­ca­te this.

If psy­cho­lo­gi­cal sym­ptoms are par­ti­cu­lar­ly pro­no­un­ced, we will also assess whe­ther pre­mens­tru­al dys­pho­ric dis­or­der (PMDD) may be pre­sent.

Com­mon ques­ti­ons about PMS

Which hor­mo­ne is lack­ing in PMS?

With PMS, the­re is usual­ly no spe­ci­fic hor­mo­ne that is lack­ing. Rather, it is assu­med that tho­se affec­ted are more sen­si­ti­ve to the nor­mal hor­mo­n­al chan­ges in the mens­tru­al cycle. This is also why PMS or PMDD can­not be deter­mi­ned on the basis of a sin­gle hor­mo­ne level.

When are PMS sym­ptoms at their worst?

PMS sym­ptoms typi­cal­ly occur in the days befo­re mens­trua­ti­on and can be par­ti­cu­lar­ly pro­no­un­ced short­ly befo­re blee­ding beg­ins. They usual­ly impro­ve signi­fi­cant­ly when mens­trua­ti­on starts or short­ly after­wards.

Which vit­amins are lack­ing in PMS?

PMS does not auto­ma­ti­cal­ly mean that the­re is a vit­amin or mine­ral defi­ci­en­cy. For cer­tain nut­ri­ents such as cal­ci­um, the­re are indi­ca­ti­ons that ade­qua­te inta­ke may reli­e­ve spe­ci­fic PMS sym­ptoms. Whe­ther die­ta­ry sup­ple­ments are indi­vi­du­al­ly advi­sa­ble should be asses­sed based on diet, sym­ptoms and any pre-exis­ting con­di­ti­ons.

What helps imme­dia­te­ly with PMS?

For acu­te phy­si­cal sym­ptoms, depen­ding on the sym­ptom, heat, exer­cise or sui­ta­ble pain­kil­lers may help. Rela­xa­ti­on exer­ci­s­es can pro­vi­de addi­tio­nal sup­port. Howe­ver, if sym­ptoms are regu­lar­ly seve­re, tre­at­ment should not be limi­t­ed to acu­te reli­ef; ins­tead, a medi­cal assess­ment should cla­ri­fy which lon­ger-term the­ra­py is appro­pria­te.

Can PMS be mista­ken for pregnan­cy?

Yes. Sym­ptoms such as breast ten­der­ness, fati­gue or mood swings can occur both befo­re mens­trua­ti­on and in ear­ly pregnan­cy. If your expec­ted peri­od does not start, a pregnan­cy test can pro­vi­de cla­ri­ty.

Can PMS get worse with age?

PMS sym­ptoms can chan­ge over the cour­se of life. Some women report stron­ger pre­mens­tru­al sym­ptoms, par­ti­cu­lar­ly during peri­me­no­pau­se. At the same time, other sym­ptoms may occur during this pha­se of life, so a pre­cise distinc­tion may be useful.
