Sexual violence occurs throughout the world. A simple definition is any sexual act for which consent is not obtained or freely given, according to the Centers for Disease Control and Prevention (CDC). Rape, sexual coercion, and unwanted sexual contact are a few examples.

While many people heal fully in time, traumatic events like these may contribute to long-lasting health issues such as heart disease, gastrointestinal disorders, and certain mental health conditions. Being aware of these possibilities can help you — and your health care clinicians, if you choose to share with them — identify and respond to health issues promptly.

Our trauma doesn’t have to define us. Knowing how to get proper treatment and support can help people who have experienced sexual violence live fulfilling, healthy lives.

Who is affected by sexual violence?

Statistics vary on different forms of sexual violence. One in four women and one in 26 men in the US report rape or attempted rape during their lifetime, for example.

Anyone can experience sexual violence. But it disproportionately impacts certain groups, such as women, people who are racially or ethnically marginalized or who identify as LGBTQ+, and people with low incomes.

Possible emotional effects of sexual violence: What to know

Most people who experience sexual assault report that it affects their mental health. Depression and anxiety are very common after sexual assault. So is post-traumatic stress disorder (PTSD). A review of multiple studies estimates that 75% of people have symptoms of PTSD within a month of the incident, and about 40% continue to have PTSD one year after the incident.

PTSD symptoms may include

• flashbacks
• distressing or intrusive memories or nightmares
• severe anxiety
• dissociation.

People with PTSD may feel numb, angry, helpless, or overwhelmed. They may also avoid triggers that remind them of the traumatic event, like certain places, smells, or objects.

Remember, your mental health is an important part of your overall health and well-being. Consider finding or asking for a referral for a mental health specialist who specializes in trauma-focused psychotherapy. This might include cognitive processing therapy, exposure-based therapy, or eye movement desensitization and reprocessing (EMDR) therapy.

Possible health effects following sexual violence: What to know

Sexual violence can have immediate health effects, of course, and reaching out to get help is important.

Yet weeks, months, or even years later, some — though not all — people develop health issues related to their trauma. Research suggests sexual violence may increase risk for some chronic health conditions, such as

• heart disease
• diabetes
• high blood pressure
• chronic pain, including pelvic pain
• frequent headaches or migraines
• irritable bowel syndrome
• substance use disorder, including opiate use.

Seeking treatment can support your healing and well-being. Consider talking to your health care provider if you think you may be experiencing any of these symptoms or conditions.

How do I talk to my doctor about my history of sexual assault?

It’s important to feel safe and comfortable with your health provider. Here are four helpful tips to consider when seeking health care:

• Ask about trauma-informed care. While sometimes your choice of provider is limited, you may be able to ask to see a clinician who provides trauma-informed care. Trauma-informed care acknowledges how trauma impacts our health and promotes an individual’s sense of safety and control.
• Share as little or as much as you like. If you’re comfortable, you can tell your clinician you have a history of sexual assault or trauma. It is your choice whether you want to discuss your trauma history with your health professional. If you choose not to, you can still seek care for any health issues related to your sexual assault. This is a confidential part of your medical record, like any other part of your medical history.
• Starting a conversation. If you decide to share, you can start the conversation with one of these examples:
  • “I want you to know I have a history of trauma.”
  • “My trauma continues to affect my health today in [insert ways].”

If the provider asks follow-up questions about your traumatic experience, know that you can provide as little or as much detail as you feel comfortable sharing.

• Medical record confidentiality. Ask if your health care institution provides any extra levels of confidentiality for your medical record. Sometimes, this includes additional access restrictions or passwords to enter your health record. This can be especially important if you have an abusive partner, or another person that you are concerned will try to inappropriately gain access to your medical records.

How can you prepare for a physical exam and talk to a clinician?

• Know that you have choices. A physical exam may help you get care you want or need to address a health issue. Yet sometimes people who have been sexually assaulted find physical exams stressful, difficult, or even traumatic. If your clinician would like to perform a physical exam, know that you can always decline or schedule it for another day or time.
• Consider having a support person present. Sometimes a support person like a good friend may make you more comfortable during your visit or exam. You can also ask the provider to have a second staff member in the room, and request a gender preference.
• Ask the provider to explain things before each step. Before the exam, you can ask the clinician to make sure you understand the steps of the exam. Remember, you can choose to pause or stop the exam at any time.
• Your consent matters. No matter the setting, you always have the right to decide how and when your body is examined and/or touched. All health care providers are held to professional and ethical standards to protect your rights. If a clinician violates this, you have the right to report the incident to the health care employer and/or local law enforcement, and to seek care elsewhere.

A few final thoughts

Sexual violence is never okay under any circumstances. If this has happened to you, know that it is not your fault.

Traumatic experiences like sexual assault can affect the body and mind. They may increase the risk of long-term health issues such as PTSD, depression, substance use disorder, high blood pressure, and chronic pelvic pain. Yet all health conditions related to sexual assault can be effectively treated. And most people who experience trauma heal and go on to live meaningful, fulfilling lives.

If you’ve ever tried to lose excess weight, you’ve probably gotten this advice: drink more water. Or perhaps it was more specific: drink a full glass of water before each meal.

The second suggestion seems like a reasonable idea, right? If you fill your stomach with water before eating, you’ll feel fuller and stop eating sooner. But did that work for you? Would drinking more water throughout the day work? Why do people say drinking water can help with weight loss — and what does the evidence show?

Stretching nerves, burning calories, and thirst versus hunger

Three top theories are:

Feel full, eat less. As noted, filling up on water before meals has intuitive appeal. Your stomach has nerves that sense stretch and send signals to the brain that it’s time to stop eating. Presumably, drinking before a meal could send similar signals.

• The evidence: Some small, short-term studies support this idea. For example, older study subjects who drank a full glass of water before meals tended to eat less than those who didn’t. Another study found that people following a low-calorie diet who drank extra water before meals had less appetite and more weight loss over 12 weeks than those on a similar diet without the extra water. But neither study assessed the impact of drinking extra water on long-term weight loss.

Burning off calories. The water we drink must be heated up to body temperature, a process requiring the body to expend energy. The energy spent on this — called thermogenesis — could offset calories from meals.

• The evidence: Though older studies provided some support for this explanation, more recent studies found no evidence that drinking water burned off many calories. That calls the thermogenesis explanation for water-induced weight loss into question.

You’re not hungry, you’re thirsty. This explanation suggests that sometimes we head to the kitchen for something to eat when we’re actually thirsty rather than hungry. If that’s the case, drinking calorie-free water can save us from consuming unnecessary calories — and that could promote weight loss.

• The evidence: The regulation of thirst and hunger is complex and varies over a person’s lifespan. For example, thirst may be dulled in older adults. But I could find no convincing studies in humans supporting the notion that people who are thirsty misinterpret the sensation for hunger, or that this is why drinking water might help with weight loss.

Exercise booster, no-cal substitution, and burning fat demands water

Being well-hydrated improves exercise capacity and thus weight loss. Muscle fatigue, cramping, and heat exhaustion can all be brought on by dehydration. That’s why extra hydration before exercise may be recommended, especially for elite athletes exercising in warm environments.

• The evidence: For most people, hydrating before exercises seems unnecessary, and I could find no studies specifically examining the role of hydration to exercise-related weight loss.

Swapping out high calorie drinks with water. Yes, if you usually drink high-calorie beverages (such as sweetened sodas, fruit juice, or alcohol), consistently replacing them with water can aid weight loss over time.

• The evidence: A dramatic reduction in calorie intake by substituting water for higher-calorie beverages could certainly lead to long-term weight loss. While it’s hard to design a study to prove this, indirect evidence suggests a link between substituting water for high-cal beverages and weight loss. Even so, just as calorie-restricting diets are hard to stick with over the long term, following a water-only plan may be easier said than done.

Burning fat requires water. Dehydration impairs the body’s ability to break down fat for fuel. So, perhaps drinking more water will encourage fat breakdown and, eventually, weight loss.

• The evidence: Though some animal studies support the idea, I could find no compelling evidence from human studies that drinking extra water helps burn fat as a means to lose excess weight.

The bottom line

So, should you bump up hydration by drinking water before or during meals, or even at other times during the day?

Some evidence does suggest this might aid weight loss, at least for some people. But those studies are mostly small or short-term, or based on animal data. Even positive studies only found modest benefits.

That said, if you think it’s working for you, there’s little downside to drinking a bit more water, other than the challenge of trying to drink if you aren’t particularly thirsty. My take? Though plenty of people recommend this approach, it seems based on a theory that doesn’t hold water.
