Chronic fatigue Even if you get enough sleep, eat right, and exercise, you might still be exhausted. This may be a red flag if your energy is the most depleted after you spend time with the guy you’re with. Think about whether you were feeling fine beforehand, only to feel exhausted after spending time in his company.^{[1]

- Clinical psychologist Asa Don Brown, PhD, DNCCM, FAAETS, believes that red flags like physical signs relate to “behaviors, attitudes, and perceptions that are toxic. Red flags are the body's subconscious and conscious warning signals relating to dangers, threats, hazards, or the potential therein.”^{[2]

Headaches, especially long-lasting migraines that ruin your day, can sometimes be linked to mental stress. Ongoing stress and anxiety from an unhealthy relationship can cause your body to produce stress hormones, which activate your nervous system in negative ways, like tension headaches and migraines.^{[3]

Digestive issues Stress from your relationship can become apparent because of the mind-gut connection, which is the way your digestive tract and your brain communicate. Being in an unhealthy relationship may manifest as stomach cramps, bloating, feelings of nausea (also sometimes linked to anxiety nausea), vomiting, constipation, or diarrhea.^{[4]

Lack of appetite Chronic stress from a toxic relationship or one with a narcissist can trigger a fight-or-flight response, which can release cortisol and/or adrenaline hormones that can suppress your appetite. Whether you experience high-anxiety encounters with your partner or a low-grade level of anxiety all the time, both can take their toll on how much you eat, leading to unhealthy eating habits.^{[5]

- Gaining weight suddenly might also be related to not properly dealing with anxiety or stress you feel from a relationship that isn’t working.
If you start to notice your lower back hurting, tension in your shoulders or jaw, or any sudden pain or ache, it could be related to your relationship. The stress hormone cortisol regulates inflammation in the body. It also helps you respond to stress. Chronic stress from a toxic relationship can keep you in a “stress response” state, which can lead to pain and muscle tension in your body.^{[6]

Stress from a toxic relationship can also cause changes in your body’s chemistry that could result in a sudden outbreak of acne or other skin issues. The same “fight or flight” response may produce too much cortisol, which can show up as acne, itchy skin, rash, or hives. Stress you may be experiencing from your relationship can also affect your skin if you’re spending less time taking care of yourself, sleeping less, eating unhealthy foods, skipping exercise, or not washing your face daily.^{[7]

When you’re overly stressed, your body produces too much stress hormone (cortisol), which can also lower your estrogen levels. Low estrogen is linked to irregular periods, weight gain, hot flashes, night sweats, fatigue, and moodiness. ^{[8]

While intense feelings of love or anger can cause heart palpitations, so can stress and anxiety. If you’re constantly in conflict with your partner or arguing all the time, your body will start to move into a fight-or-flight response, causing your heart to beat faster and can even lead to a panic attack.^{[9]

Chronic stress from a toxic relationship can increase hormones that disrupt the hair growth cycle. When stress causes hair loss, it’s often temporary and may disappear when leaving a very negative relationship or experience.^{[10]

When you just can’t relax or feel panicked all the time (or super high energy without being productive), it could be underlying stress that is making you feel restless. Often, you may find yourself staying busy, performing unnecessary tasks, or doing extra work so you’re never alone with your thoughts. Your relationship could feel unstable or simply emotionally draining.^{[11]

Chronic stress can weaken your immune system, which makes you more susceptible to things like colds, flus, or stomach viruses. If you seem to always be sick, but can’t figure out why, your relationship could be to blame. See a health professional for a full workup.^{[12]

Negativity in a relationship can be a major factor affecting how much or how well you sleep. Dealing with anxiety, depression, or unresolved conflict in your relationship is difficult and may cause you to have trouble falling asleep or staying asleep.

Emotional signs can also point to an unhealthy relationship. If you can’t concentrate at work, are extra moody with friends and family, or can’t relax at home, you may be experiencing feelings of anxiety, low self-esteem, or depression. These signs may be related to your relationship, and you might experience:
- Irritability: You’re always in a bad or annoyed mood, especially around your S.O.
- Emotional distance: You feel emotionally disconnected from people, places, and things around you.
- Lack of attraction: You’re not as interested in being intimate with your partner, or you avoid it.
- Depression: Your mood is often sad or hopeless; you find yourself crying for no reason.
- Lack of focus: You have trouble concentrating on work, friends, or yourself; you’re always in a state of worry and brain fog.
- Panic: You feel panic even if you aren’t in immediate danger.
- Relationship coach John Keegan suggests that anxiety is usually just “your intuition telling you ‘something's not right about this for me.’”^{[13]

Get support from a friend or family member you trust. Lean on those you love most by talking to them about your issues, feelings, and the relationship itself. In some cases, you might find the solution is more obvious than you think.^{[16]

Take care of yourself. Reduce stress through relaxation, and make time for self-care through rest, meditation, yoga, or time apart from your partner. If trying to ease stress and tension just isn’t working, consider what next steps you need to take for your health and wellbeing.
- Always talk to a health professional if you have any serious concerns about your health.
4
Talk to a therapist or counselor for guidance. If you need a professional to help you work through your issues, consider seeking the help of a licensed psychologist or therapist. They may be able to better help you identify triggers leading to your physical issues, and make it easier to decide how to address them.^{[17]

- If you decide that your relationship is worth staying, encourage your partner to attend couples therapy with you so you can both work on your issues, or know when it’s time to break up.
5
Make a plan to end the relationship if you’re unhappy. If you know it’s time to walk away from your relationship, take steps to break up with your partner. Meet with him in a safe place or bring a friend along if you need support. Be direct when telling him that you need to end the relationship. Be honest about the stress you’re feeling, and how it’s manifesting physically and emotionally, if you feel comfortable doing so. Listen to what he has to say, but avoid getting into lengthy arguments over blame.
- Stand firm in your decision and give yourself time to heal and grow from the experience.^{[18]
